mchk gives "Segmentation fault"

The problem is, mm_wrapper is SGID (suid Group) as the wrong user. mm_wrapper, in your case, is currently SGID 101 (see what group that is in /etc/groups), which mailman doesn't like.

Anyway, look at mm_wrapper (it's in the qmail/bin folder). Here's mine (on FreeBSD, which is a different path from Linux):

ls -l /usr/local/psa/qmail/bin/mm*
-r-xr-sr-x 1 root popuser 4880 Aug 24 08:15 mm_wrapper

Just as a test, make a backup copy, saving the original owner & permissions with the -p flag:

cp -p mm_wrapper mm_wrapper.orig

That way you can "cp -p" the original back over your mm_wrapper if it doesn't work.

OK, now double-check which group is 110 in your /etc/group file. It should probably be "popuser". If so, change the group on the mm_wrapper file to popuser:

chgrp popuser mm_wrapper

... finally, stop and restart qmail, and see if your problems go away. Hopefully so.
 
We tried this.

Doing a tail -f on the maillog gets us this error:

Code:

This is really becoming a pain in the proverbial whatchacallit.
 
Same problem here, even after applying the hotfix.

CentOS 4.2
PSA 7.5.4-rhel4.build75050824.12

"segmentation fault" when running mchk -v

This is a problem; because we can't perform the mailman GID fix in the knowledge base (http://kb.swsoft.com/article_61_942_en.html) without the ability to run mchk. :-(
