[Dovecot] Re: Hang in 1.0.alpha4

[Martin Preen]

Hello,
it looks like that one user seems to have the same problem. After some
time the IMAP-process enters a poll loop and the client hangs. It is
the same with 1.0stable and 1.0alpha4 (on Solaris 9).

Is this already fixed in CVS or should I wait for 1.0alpha5 ?
