[Dovecot] More core dump stack traces

[Lloyd Parkes]

Hi all,
I found a whole bunch of core files from imap this evening, so here  
are the stack traces from each. Unlike my last message, I don't have  
debugging symbols for these, so there isn't any analysis I can easily  
do. There were several cores with the first stack trace and one with  
the second trace. The core dump for the second trace is the only one  
I noticed. I suspect that the first trace happens when the client  
host goes to sleep. If so, the situation needs to be handled more  
gracefully. I'm currently building a copy of imap with debugging  
symbols.
