I tried the core dump method from the above link, but without luck. Here
is what I did:
1. vi /etc/dovecot.conf
mail_drop_priv_before_exec = yes
mail_debug = yes
# the rest is untouched
2. ulimit -c unlimited
3. service dovecot restart
4. echo 'core.%p' > /proc/sys/kernel/core_pattern
I noticed this in the maillog this morning:
Sep 24 07:34:20 mail dovecot: child 492 (auth) killed with signal 11
But there isn't any core dump found in the whole file system. Then I
doubted there's maybe some setting problems and did the following:
echo '/tmp/core.%p" > /proc/sys/kernel/core_pattern
ulimit -c unlimited
/etc/init.d/dovecot restart
ps aux | grep dovecot-auth
kill -s 11 <pid_of_dovecot_auth_found>
And there still isn't any /tmp/core.* found. Is there any other way I
can try?
