Hi all,
Our IMAP server was running for about 14 days without problems (we pilot phased it for about 7 days which worked fine) we got the following
exception (found in james-server.log, not imap-server.log):
-----------------------------------------------------------------------------
INFO 15:24:56,926 | james.mailetcontext | Error while storing mail.

stack trace at which the context was closed is available if
Runtime=TRACE logging is enabled.

-----------------------------------------------------------------------------
It seems difficult or quite impossible to reproduce this because the error only happens sporadically. Our solution was to turn off IMAP, and
use POP3 instead - but this solution does not really work. Without looking at the code a possible solution would be easy to implement, e.g.
just check whether the context is open before using it, otherwise retrieve a new context.
I found some solutions to this problems here:
-
http://forum.springsource.org/showthread.php?50135-OpenJPA-and-closed-context
Is there any timeout value for the context which we could increase?
Thanks for any help on this issue.
Best regards
Michael
