Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Scott Mullen (smullen27) Assigned to: Nobody/Anonymous (nobody) Summary: Package Memory Leak in Parser Initial Comment: I'm running openser 1.3.0 currently and I think I've discovered a memory leak in the parser code. I've recompiled the code already to use the debug option DBG_QM_MALLOC. I've taken an initial snapshot of the memory right after startup. I've also taken 4 additional snapshots after some load has been running on the box. For each of the additional snapshots, I've let all of the load run off of the box prior to taking the snapshot. A gzip'd tar file can be downloaded from: http://mullen.dyndns.org/openser/OpenserMemory.tar.gz threadDump.0508-HHMMSS-1.txt (actual dump from kill signal) threadAnalysis.0508-HHMMSS-1.txt (counts of each instance in pkg memory from the dump file) threadAnalysis.0508-153951-1.txt threadAnalysis.0508-164349-1.txt threadAnalysis.0508-164600-1.txt threadAnalysis.0508-165217-1.txt threadAnalysis.0508-170038-1.txt threadAnalysis.0508-181908-1.txt threadDump.0508-153951-1.txt threadDump.0508-164349-1.txt threadDump.0508-164600-1.txt threadDump.0508-170038-1.txt threadDump.0508-181908-1.txt threadDump.0508-165217-1.txt I can also attach gdb to the process to print out anything that could be helpful as well. ---------------------------------------------------------------------- >Comment By: Scott Mullen (smullen27) Date: 2008-05-09 14:51 Message: Logged In: YES user_id=2082554 Originator: YES I've attached two call flows that are causing the memory leaks. Looks like there are "bad" UA's on either side of openser for this, but none-the-less this should not cause a leak. CallFlow1.txt: All Invites below the Initial Invite->200 OK->ACK are Re-Invites with the same callid, same To tag, same From tag and same CSEQ. CallFlow2.txt: All of the Invites in this call flow are Initial Invites with the same callid, same From tag, Same CSEQ and NO To tag. Sorry about the formatting of these text files. They are dumped out of wireshark to a text file and the format is not perfect, but you can make sense of them.
