Package: collectd Version: 4.10.1-1+squeeze2 Severity: important
When running collectd with the "processes" plugin on a kFreeBSD kernel, I noticed that it complains about a "double free or corruption" and then fails to stop properly after hitting Ctrl-C. I am forced to use kill -9. root@debian:~# egrep -v '^$|^#' /etc/collectd/collectd.conf FQDNLookup true LoadPlugin processes Include "/etc/collectd/filters.conf" Include "/etc/collectd/thresholds.conf" root@debian:~# collectd -f *** glibc detected *** collectd: double free or corruption (top): 0x00000000006390b0 *** Initialization complete, entering read-loop. ^CExiting normally. collectd: Stopping 5 read threads. ^C Killed When running in test mode (-T), collectd dumps a core file: root@debian:~# collectd -T *** glibc detected *** collectd: double free or corruption (top): 0x0000000000634be0 *** Aborted (core dumped) root@debian:~# gdb /usr/sbin/collectd /var/lib/collectd/collectd.core GNU gdb (GDB) 7.0.1-debian Copyright (C) 2009 Free Software Foundation, Inc.

I didn't test any other architecture. Thanks !
