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.

This problem doesn't occur on squeeze's Linux (amd64) kernel. I didn't test
any other architecture.
Thanks !

I tested collectd 5.1.0-3 as well as 4.10.1-1+squeeze2 on a freshly
installed debian-kfreebsd (kernel version 9.0-2). I also was unable to
reproduce this issue. I believe you are right: this problem was related to
kfreebsd itself, not collectd. I'm closing this bug. Thanks !
Cheers,
Marc
