Sometimes my server uses for some minutes much more memory than it should - and I guess it's dbmail. I hope I'll find some time soon to use a profiler, but meanwhile I guess the following happens: someone marks a mailbox for offline use and dbmail-imapd does the following: - fetch all mails from database - keep the result set in memory - deliver them The third step can take a while so the process eats lots of memory for quite some time - no bug, its a design problem. This only happens for some minutes, that's why I'm quite sure it's no memory hole. The way to go would be to use a server side cursor so only one mail has to be kept in memory - but AFAIK there's a storage system with SQL interface (sorry couldn't resist) that doesn't support cursors. ====================================================================== Bug History Date Modified Username Field Change ====================================================================== 12-Dec-04 00:27aaron New Bug ======================================================================
