SIGPIPE happens if some socket goes down. This can be one of those:
a) Apache=>SOGo socket
b) LDAP connection
c) IMAP4 connection
d) PostgreSQL connection

Its a bit hard to debug if we can't reproduce it though :-/

Weird. Please file a bugreport.

Its not unusual that signal handler bugs corrupt memory, so maybe there 
is some bug in there. But of course the real question is why the 
SIGPIPE occurs in the first place.

One thing to do for you: if you have a sogod instance running for some 
two days, list the file descriptors which are opened by the process 
(using lsof as root).
Attach that to the bug. Maybe we can see what connections are still 
open and might go down.

It would be best if SOGo instances would recycle themselves once a day 
automagically.
