[Dovecot] dovecot:IMAP(user) killed with signal 6

Mon Nov 20 14:36:13 UTC 2006

Thanks Timo!

Since I've been running rc10 again dovecot stopped aborting.

By the way, when I used the create_shares.pl script, it created a
symlink for every file in the directory to be shared. Simple
symlinking the dir seemed to 'almost' work but for the keyword file
errors.

Upgrading to rc15 fixes the problem as well, the Permission Denied
message still comes up, but dovecot no longer aborts.

Will try the create_shares.pl script again and see where my
symlink-config is wrong.

FWIW I wouldn't want any undocumented behaviour in dovecot just
because I'm a stupid twat...

Kind regards,

Spil.
