Description sylwester 2008-04-02 20:40:00 UTC 
collectd 4.1.2 segfaults in FreeBSD 7.0

Recompiling collectd with debug-flags and debugging it with gdb:

Program received signal SIGSEGV, Segmentation fault.
0x00000000407c47ec in memcpy () from /lib/libc.so.7

Make this a ports PR.
Comment 2 Daniel Roethlisberger 2008-05-05 16:46:02 UTC 
This seems to happen with some (mis-)configurations and/or plugin
failures.  For instance, the CPU plugin seems to crash with more than
one CPU cores.  Try tweaking the configuration to find out which module
or which statement triggers the segmentation fault.

I will try to take care of segfaults when updating collectd to the
latest release, which I plan to do within the next few weeks.

This patch solves the problem on sparc64:
pcap_open_live segfaults inside libc's memcpy if pcap_device is NULL.

I haven't been able to reproduce it on i386, though.

P.S. Maybe we should consider investigating why it fails on sparc64 but
not on i386 in the first case?
