Too Many Open Files
Hello,
Running James 2.0a2 on Windows 2000, using the filesystem as the
repository. When there are lots of messages for a user (problem
is seen somewhere between roughly 1000-2000 messages), an error is
returned when the user tries to retrieve these messages via POP.
From the server logs, this error appears to have something to do with
"too many open files".
When I last saw this, I stopped James and moved (the newest) 1/2 of the
files from the user's inbox folder to a temporary folder. Restarted James,
and was able to download the oldest messages. I then stopped James,
restored the files from the temporary folder back to the inbox, and was now
able to download these newest messages.
Is this a known issue? Is there anything I can do to avoid the problem
(besides more frequent downloading of emails)? Will an upgrade to 2.0a3
help?
Stephen

There was a bug in MimeMessageSource (InputStreams were not closed), which was fixed in May.
Try to use a newer version of James.
