Thats on an unpatched server.. default 1.1.2 code. It seems to be a very rare occurance.
Looks like I managed to reproduce it in about 5 minutes with the original cache timeouts. imaptest reported that several commands were hanging for over 60 seconds then. I'll try to figure out if this can be prevented.
This should fix it: http://hg.dovecot.org/dovecot-1.1/rev/7772018e917c
This is completely seperate from your previous patches?
