I recently upgraded my development server to FreeBSD 8.0-PRERELEASE (which has
since been released). I started to notice this error from time to time:
Nov 29 15:35:00 ngaio kernel: pid 91715 (mailwrapper), uid 1001: exited on signal 11 (core dumped)
After mentioning the error on IRC, it was suggested that my recent buildworld
had overwritten my installed Postfix binaries. To fix the situation, I rebuilt
portupgrade -f postfix
To prevent this from happening again, the following was added to /etc/src.conf
(a file which did not exist, so I created it):
The next build world will not build the mail wrapper or sendmail. This will
save a bit of time during the process, but save me from this headache again.
Thanks qbit for pointing this out.
