[collectd] collectd 4.5.4 - segfault after setting time

[Vogt, Michael]

Hey 

The assumption that the error is related to the openipmi plugin is
wrong. However, i could reproduce the segfault with this little script:

---
/etc/init.d/ntpd stop
ntpdate ch.pool.ntp.org

-- start collectd here

/etc/init.d/ntpd start
date 051909592022.59

wait ~10s
segfault

The config file for collectd (stripped down version) can be found here:

/root/exec.sh is a stub file and looks like this:

echo PUTVAL localhost/exec-interface/gauge-eth2 N:0
echo PUTVAL localhost/exec-interface/gauge-eth3 N:0

A full backtrace is attached to this mail and called collectd.conf.log.


I also attached other backtraces i collected. I used the "normal"
collectd.conf file with the rrd output (im using rrdtool v1.2.27 btw).
But the segfault also happens if i disabled all output plugins. To make
this even more strange, the segault sometimes disaperars if i add /
remove a threshold item or add the logger plugin.


I also had sometimes a broken pipe signal (broken-pipe.log) due the
notification script, i let the program continue - then it segfaultedt
(post-broken-pipe-segfault.log).

I dont have any ideas left - i hope someone can help me!

Cheers
Michael
