I'm not sure how the "test" function works, but I'm assuming it probably just opens the number of connections you specified without doing much real work, like attempting to select the same folder with two connections. The problem in this situation is your IMAP server doesn't support multiple connections accessing the same mail box. This isn't too uncommon, especially not on imap servers that use a single file to store messages (ie mbox), as it cannot allow two sources modify the same single file at once. Looking at the above log messages, the initial connections are established, and the threads run off to do their STATUS check to find out the message count etc. At which point you're selecting the tbbeta folder as it is attempting to do a count. There is another time you can get this kind of message... When you are receiving a message into that folder at the same time you are attempting to select it. The SMTP service will cause a mailbox lock at the same time you're trying to acquire a read lock. You could try reducing the chances of collisions on the connections by reducing the count to maybe 2, and setting one dedicated to loading messages, and see if that helps. I unfortunately cannot confirm your views on the instability of IMAP in RC4, as I have been using it just fine for a bit, but then again, I don't have an IMAP server that requires locking, at least not on the whole mailbox, but single files might be a possibility (Maildir format). -- Jonathan Angliss <[EMAIL PROTECTED]>
