[Dovecot] Exim+Dovecot LDA - How can I catch the crash?
Hello list
I am testing mdbox with Dovecot from http://hg.dovecot.org/dovecot-2.0-sis/.and
my MTA is Exim. It appears to crash, but I am not sure how to capture the
actual crash.
What I get in Exim logs is:
2010-07-28 19:55:13 1Oe9uT-000KmG-Oz ** /var/spool/virtual/
titan.co.ke/wash/Maildir <wash at titan.co.ke> R=virtual_domains
T=dovecot_virtual_delivery: Child process of dovecot_virtual_delivery
transport (running command "/opt/dovecot2/libexec/dovecot/deliver -d
$local_part@$domain -f $sender_address") was terminated by signal 11
(segmentation fault)
This crash does not happen with RC3 of Dovecot. I know I shouldn't be using
bleeding edge code, but strangely enough, I need to use this one to satisfy
my curiosity, and to help me learn one or two new tricks.
With rc3, here is what I have in dovecot.log:

Attached is my doveconf output.
I need to find out what is killing the lda.

Well, if so, then I am still at the same point.
