The TCP/IP IMAP server has experienced a runtime error. The reason
for the error should appear on the subject line of this message.
Please investigate this problem as quickly as possible.
Thank you.

Here is the TCPIP$IMAP account. Careful reading, rereading, and rerereading has not revealed to me whether any of these settings could possibly be insufficient on a two-user mail system:

I have tried enabling trace, but it doesn't even indicate when these crashes occur.
Even when the server doesn't crash entirely, it is very unstable. My best interpretation of the documentation is that the server has memory leaks and has been patched to work around them by periodically creating new processes. It seems that when it does this, it silently stops communicating with the client for "up to five seconds." Mozilla Thunderbird does not like this and sometimes either fails to refresh a folder or shows a blank folder. Twiddling Max-Connections from 25 to 50 to 100 to 10 and even 1 doesn't make a difference other than making the glitches change slightly in frequency.
IMAP also creates new versions of emails-- emails which have not been modified by the user. This causes the email directory to become more cluttered and IMAP even slower (and it is already quite slow with more than 40 or 50 messages in a folder). I must periodically purge these files, which can number in the hundreds within a month.
Is there anything I can do to get basic stability out of this product, or should I move to the byzantine but allegedly stable PMDF?
Solved! Go to Solution.

Re: TCPIP 5.5 IMAP Server nonexistent stability
Research into older threads finds that IMAP broke in one of the 5.4 ECOs, but I can't even download any of the earlier 5.4 ECOs from anywhere and use the image just to see if it works.

Re: TCPIP 5.5 IMAP Server nonexistent stability
Please don't forward engineering "hotfix" images to others. They haven't been through the normal QA processes and the intention is that engineering and services can track where they are in case problems are discovered.
Treat them like a prescription drug. By all means refer someone you think may have the same symptom to the doctor who prescribed it to you, but please don't just give them your treatment.
Stephen, to have your symptom diagnosed, and possibly obtain the same image as described by Jerry (or maybe a different one tailored to your circumstances), please log a case with your local customer support centre.
