Yet there's one issue that none of the updates have resolved. The last time I reported it we were running 2.2.12. Now we're running 2.3.8, but the issues is the same: POP and IMAP processes that use TLS/SSL get "stuck". My observations point towards dropped dial-up connections as the cause. Here's an example:Have you tried setting `tls_session_timeout' to zero in imapd.conf to disable caching of TLS sessions?
No. While it's possible that there's some connection, I don't see it from the stack trace. I think I'd like some indication from one of the developers that caching *could* be the cause before I try that.
I believe that that solved the problem for me, although it happened rarely. I only use `berkeley-nosync' for `duplicate_db' and `tlscache_db', but I suspected that the problem was the result of a database deadlock.
We use skiplist, which to my mind makes it even less likely that that's the cause ... thanks for the suggestion anyway.
