Description FiLiS 2024-08-12 14:07:11 UTC 
After upgrading to the latest version of the port, we're seeing a lot of SIGPIPE warnings in the php-fpm.log:

[12-Aug-2024 15:56:27] WARNING: [pool www] child 13282 exited on signal 13 (SIGPIPE) after 5.575445 seconds from start
[12-Aug-2024 15:56:27] NOTICE: [pool www] child 13325 started
[12-Aug-2024 15:56:33] WARNING: [pool www] child 13325 exited on signal 13 (SIGPIPE) after 5.099562 seconds from start
[12-Aug-2024 15:56:33] NOTICE: [pool www] child 13328 started
[12-Aug-2024 15:57:08] WARNING: [pool www] child 11939 exited on signal 13 (SIGPIPE) after 216.912813 seconds from start
[12-Aug-2024 15:57:08] NOTICE: [pool www] child 13674 started

even on systems that aren't crazy busy, this happens. We don't see user-facing errors in the logs, though. Sometimes nginx logs a 499 error, probably during the child restart.

Any clues on where that could come from?
Comment 1 FiLiS 2024-08-13 08:11:10 UTC 
Could this be related to the libxml2 patch from https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=280153 ?
I have downgraded one box to PHP 8.1.29 from before July 27th and the SIGPIPE errors went away.

Looks like it might be due to the libxml patches. In a very unlikely case if this is a showstopper for libxml update we might have to kill it even before it reaches it's EOL. :(

I will look into upstream.
Comment 3 FiLiS 2024-08-21 14:16:29 UTC 
thank you for looking into it. It looks like the patches are only for libxml 2.12, while the current textproc/libxml2 port is 2.11, so PHP 8.1 could do without those for now as long as the libxml2 port isn't update beyond 2.12, right?

    lang/php81: Disable the libxml2 patches

    Some patches were added for supporting libxml2 2.12 or newer however as
    libxml2 itself has not yet been updated these patches are not compatible
    with the previous versions and have runtime issues. These patches should
    be added again after textproc/libxml2 has been updated to 2.12 or newer.

    On the contrary if php81 has runtime issues even after the libxml2
    updates and with these patches we might have to remove php81 earlier
    than expected if there is no fix.
