I tried Dovecot 1.2.beta1 yesterday. I had been using 1.1.11.
I started getting "Panic: POP3(xxx): Trying to allocate 0 bytes"
There are two kinds of pop3 users. In the attached log.txt file, user
u1 is using a pop3 MUA. For users u2, u3, u4 and u5 fetchmail is
coming through an ssh tunnel and retrieving their mail.
u1 is able to interact normally with dovecot, but the fetchmail users
encountered the panics in the log.
dovecot -n is attached as dovecot-n.txt. At first I thought it was a
locking issue as .lock files were being left behind, so I changed
pop3_lock_session to no, and restarted dovecot, but this didn't help
so I reverted to 2.1.11.
