The following issue has been SUBMITTED. ====================================================================== http://www.dbmail.org/mantis/view.php?id=462 ====================================================================== Reported By: fehuq Assigned To: ====================================================================== Project: DBMail Issue ID: 462 Category: IMAP daemon Reproducibility: always Severity: major Priority: normal Status: new target: ====================================================================== Date Submitted: 29-Nov-06 15:13 CET Last Modified: 29-Nov-06 15:13 CET ====================================================================== Summary: imap daemon appears to leak memory on FETCH command Description: I delivered several thousand messages to an account on a test server, and set up an IMAP account in Thunderbird to access it. Thunderbird ran its junkmail controls on the folder, which issues a FETCH command for each message. I noticed later that the dbmail-imapd child process handling my connection had used almost all of the system's free memory and swap.
As best as I can tell, the process usually doesn't free memory used after a message is fetched. I'm attaching a text file containing top's output of the process at 3 second intervals. The memory usage does drop a bit in some of the intervals, but overall it gets large fairly fast. Killing, or having dbmail restart the child process after 1 connection does successfully free the memory, though. The pop server does not show the same behavior. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 29-Nov-06 15:13 fehuq New Issue 29-Nov-06 15:13 fehuq File Added: top_3sec_interval.txt ======================================================================
