RPOP giving up

[Duncan Hardy]

We use RPOP to retrieve messages from some Internet based mailboxes.
Recently users have been not getting new mail because their RPOP
requests have stalled. After a failed attempt to connect to the ISP
(presumably because their server is overloaded or something) RPOP seems
to give up altogether, instead of retrying a few minutes later. This is
specific to each user+connection. Other RPOP connections, even for the
same user reschedule as normal.

Is this normal behavior? Can I force CGP to keep retrying? Is it
possible to reset the RPOP module periodically via the command line?
(ie similar to what happens if you update the users RPOP config).

Thanks,
Duncan
(CGP 5.3, Windows 7)

This is a bug confirmed for 5.3. It's already fixed for 5.3.1 release.

just a short note from another site:

this seems to be a 5.3.0 specific behaviour, regardless which
platform. we're currently on linux but tested on others too.

we have a lot of customers which used RPOP for the past years
without problems. just after upgrading to 5.3.0 we got more
and more complaints about stuck RPOP configurations.

Best regards,
K.
