Hi, I've been testing dbmail for quite some time now to see if it's usable in production. The latest version (3.1.4) seems to be quite OK, except for one issue: it seems to leak pretty large amounts of memory. I have a test environment that can simulatie some heavy mail traffic being delivered via dbmail-lmtpd and then retrieved via dbmail-imapd (around 6.500 messages in 5 minutes). When I run this test, memory usage (resident size) of dbmail-imapd increases considerably with around 5 - 10Mb per testrun. This memory is never released and the process keeps growing in size and will eventually cause an out of memory of the server. I've tried both with and without 'jemalloc', but the behaviour is the same. This leak is probably masked by the fact that the logrotate script on Ubuntu/debian by default does a restart of the process every day, but when I disable this (to prevent unwanted downtime), memory usage keeps growing and growing... Is there anything I can do to help debug this? I'm running on Ubuntu 12.04, version 3.1.4, gmime 2.6.7-1.
Thanks, Ronald.
