Package: collectd
Version: 5.12.0-22
Severity: normal
X-Debbugs-Cc: mgronczew...@efigence.com
We're using collectd instance to translate from collectd protocol to
riemann so config (in attachment) is pretty simple; with enabled
write_riemann plugin we are getting segfault as soon as it starts
receiving data:
/usr/sbin/collectd -C /etc/collectd-server.conf -f
[2024-11-27 16:57:34] plugin_load: plugin "logfile" successfully loaded.
Segmentation fault
(as in it starts when I block incoming traffic in iptables but crashes
when I remove the block and traffic hits it).
weirdly enough, not on every server, but I assume that's coz traffic is
hashed and some get the type of packets that trigger that bug.
I think it might be this one
https://github.com/collectd/collectd/issues/4050
that was patched and backported to 5.12 at beginning of this year:
