Attach gdb (or whatever) to the process after authN, before select.   
I'd guess the mailbox needs to be reconstructed, for whatever reason.

I've seen that in older versions (what version are you running?), but  
haven't been able to reproduce it in recent versions.  The problem,  
generally speaking, is that master runs as cyrus, so it's can't open  
new low-numbered ports. The bug is that it thinks pop3 is a new.
