Description Andrej Ebert 2016-07-25 16:19:10 UTC
Since base r296727 of 10-STABLE and at least up to base r303255 of 11-STABLE sonarr crashes on startup with the following:

[1]    95725 abort (core dumped)  mono /usr/local/share/sonarr/NzbDrone.exe -v

The last revision it works on is base r296649, so if I'm not interpreting something wrong, the breaking commit is base r296727.

This happens both with the current version of mono in ports and also with mono version 4.4.1.0 (installed with the patch from bug 211004).

Here are other reports of the problem:

https://lists.freebsd.org/pipermail/freebsd-mono/2016-May/001973.html

https://forums.freebsd.org/threads/56249/

I also found SmartOS having (maybe) having a similar problem: https://smartos.org/bugview/OS-4732
Comment 1 Mark Felder freebsd_committer freebsd_triage 2016-07-29 19:29:22 UTC
Weird, that SmartOS bug is for their lx branded zones. We're running Sonarr/mono natively on FreeBSD.

I haven't been able to reproduce this, and my box running Sonarr is a CURRENT machine with Sonarr in a 10.2-RELEASE jail.

FreeBSD skeletor.feld.me 11.0-ALPHA6 FreeBSD 11.0-ALPHA6 #66 r302316: Sat Jul  2 10:05:43 CDT 2016     root@skeletor.feld.me:/usr/obj/usr/src/sys/GENERIC  amd64

root@skeletor:/usr/home/feld # jexec sonarr sh
# freebsd-version
10.2-RELEASE-p20
Comment 2 Andrej Ebert 2016-07-30 00:17:49 UTC
Yeah, it wouldn't manifest on 10.2, not even on 10.3 RELEASE, but try anything higher than 10-STABLE base r296649 and you'll see it :)
Comment 3 Mark Felder freebsd_committer freebsd_triage 2016-08-01 15:42:19 UTC
Is it strictly the 10-STABLE train or should I also see it on CURRENT?
Comment 4 Andrej Ebert 2016-08-04 16:30:54 UTC
(In reply to Mark Felder from comment #3)

I don't have a CURRENT machine to test, but it's definitely (still) present on

FreeBSD 199-SERVER 11.0-BETA2 FreeBSD 11.0-BETA2 #0 r303255: Sun Jul 24 11:45:56 CEST 2016     root@199-SERVER:/usr/obj/usr/src/sys/MASK  amd64

so you should see it on your 11.0-ALPHA6 outside of the 10.2 jail, or inside a 10-STABLE (beginning with base r296727) or 11-STABLE jail.
Comment 5 Konstantin Belousov freebsd_committer freebsd_triage 2016-08-05 08:25:06 UTC
There was a regression in r294373, fixed by r302908 in HEAD.  stable/11 commit was r303193, 2016-07-22. Could you try if it changes anything WRT the issue ?
Comment 6 Andrej Ebert 2016-08-05 16:57:55 UTC
(In reply to Konstantin Belousov from comment #5)

As I mentioned in my initial report, I'm still seeing this on 11-STABLE r303255, which is after r303193. I'll try the latest revision in the 11-STABLE tree, but I doubt anything'll change.
Comment 7 Konstantin Belousov freebsd_committer freebsd_triage 2016-08-05 17:52:04 UTC
(In reply to Andrej Ebert from comment #6)
Can you provide me something self-contained (e.g. binary and all required libraries, no dependencies outside base system and content of the pack) which demonstrates the issue ?

I.e. the thing should work before the revision, and fail after.
Comment 8 Andrej Ebert 2016-08-08 15:07:24 UTC
(In reply to Konstantin Belousov from comment #7)

Sorry, I really don't know how to do that.

But i did try different 10-STABLE revisions in jails, and it's fine up to base r296649, and starts crashing with base r296727 on 10-STABLE and keeps crashing at least up to 11-STABLE base r303255.

I have a slight temperature problem at the moment(need a bigger case) and can't rebuild world to go to a newer revision of 11-STABLE, but maybe someone's willing to confirm by building and trying to start sonarr in a jail or on a machine that's on a revision higher than base r296649.
Comment 9 Ivan Radovanovic 2016-08-08 15:17:48 UTC
(In reply to Andrej Ebert from comment #8)

Can you please try running this simple test case I am linking here (so we can determine if ProcessName getter is completely broken or it is some specific usage pattern that is causing Sonarr to crash).

These recompilations do not provide any value.  I need an isolated test case, then I will fix the problem.

Fantastic, thanks for providing a simple reproducible case!

Can you attach that small bit of code to the ticket?


Thanks!

@Konstantin, I suppose you need some minimal test code in C? (I will try to create one for you)
Comment 16 Andrej Ebert 2016-08-09 09:48:24 UTC
For completeness, here's the testcase with base r296649, as you see, no crash.

I'll attach the verbose output of mono separately.

(In reply to Ivan Radovanovic from comment #14)
Test case in C would be ideal, but this is probably too much work.  I am fine with some binary pack that reproduces the issue.

The only requirement is that the pack should be self-contained.  In other words, I have bare base system where I can, say, untar it into correct location and reproduce the issue.  This would be enough.

Can you please try to pull stack backtrace from this crash dump - for example:
$ gdb `which mono` mono.core 
(gdb) bt
<STACKTRACE WILL BE HERE>

Problem is that mono's implementation of pulling process name is quite complicated, this would give me pointer where to look for problem

(In reply to Konstantin Belousov from comment #17)
Unfortunately without me manually creating test case in C the only self contained test case for you would be to install mono and to try to run that attached test case (compile with "mono process_name.cs" and run with "mono process_name.exe").

So it looks very similar to the bug reported above. 

I'm running 11.0-RELEASE-p2 (GENERIC) and mono 4.6.2 (latest pkg) in a jail.

I've tried running it on the host system, with the same error.

I've also tried building from source (poudriere) and the build fails due to a similar SIGSEGV:

if test -w /wrkdirs/usr/ports/lang/mono/work/mono-4.6.2/mcs; then :; else chmod -R +w /wrkdirs/usr/ports/lang/mono/work/mono-4.6.2/mcs; fi
cd /wrkdirs/usr/ports/lang/mono/work/mono-4.6.2/mcs && gmake --no-print-directory -s NO_DIR_CHECK=1 PROFILES='binary_reference_assemblies net_4_x xbuild_12 xbuild_14      ' CC='cc' all-profiles

Any reason this bug would re-appear on a multi-processor system?
Comment 28 Phil 2017-01-25 06:26:23 UTC
After some more playing around trying to run mono both on bare metal and a VM, I've narrowed it down to what seems to be a memory issue.

I have 256G of ram in the server. If I restrict hw.physmem=140G, mono works fine. Anything above hw.physmem=150G or so seems to cause it to crash!

Changing the cpu count or cpu type (in the VM) has no impact.

Seems like something's off when there's too much memory available...

Any thoughts?

Any way you can test to see if this is reproducible in Linux as well? This should probably be covered in a separate PR as well.
Comment 30 Phil 2017-01-26 22:51:31 UTC
On Linux (Ubuntu Trusty or Zesty), mono-4.6.2.7 runs fine on a system with 256G of ram (just via apt-get).

I also built it from source on that same machine and it built without issues.
Comment 31 Walter Schwarzenfeld 2018-03-06 18:39:58 UTC
We have version 5.2.0.215. Is this still a problem?
Comment 32 Richard Gallamore freebsd_committer freebsd_triage 2018-04-08 18:08:31 UTC
(In reply to w.schwarzenfeld from comment #31)
Didn't have any issues until the moment version 5.2.0.215 landed on r460430. Iv had to hold back on updating it in production. Even installing it returns a stack trace:

The following 1 package(s) will be affected (of 0 checked):

There are all sorts of errors in the build log as well I have no idea how this hasn't been reverted yet. This is my most recent build log on current and 11-stable.

FYI, the patch [1] to update mono to 5.10 by feld@ fixes this issue.

URL: https://svnweb.freebsd.org/changeset/ports/472555

Log:
  Update Mono to 5.10.1.47

  This brings a more modern Mono release to the ports tree. After
  discussions with others in the Mono community I targeted the mono
  5.10.1.47 release which is the latest release in the "Visual Studio"
  release channel. This is considered to be the most stable and widely
  tested, which makes it a good candidate for us. We may upgrade to 5.12
  after additional testing or introduce another Mono package for users who
  require testing against a newer release; this has yet to be determined.

  - Build from official release tarballs
  - Now include BoringSSL per upstream guidelines [1]
  - Remove ACCEPTANCE_TESTS, not being updated by upstream
  - No long require glib; Mono includes their own replacement
  - USES=display:tests required for some tests
  - Remove broken for armv6, armv7: file now available [2]
  - Mark as LLD safe as mono changed how it handles TLS [3]

Fixed in feld's commit.  Thank you for the report.  Please report any issues encountered in the update to mono.
