-------------------------------------------
Summary: Memory leak during perf testing
Key: ASTERISK-25905
URL: https://issues.asterisk.org/jira/browse/ASTERISK-25905
Project: Asterisk
Issue Type: Bug
Security Level: None
Components: Applications/app_confbridge, pjproject/pjsip
Affects Versions: 13.8.0
Environment: Red Hat Enterprise Linux Server release 7.2 (Maipo)
Linux ykt1cfbprd1 3.10.0-327.13.1.el7.x86_64
certified/13.8-cert1-rc1
pjproject-2.4.5
Reporter: Robert McGilvray
Severity: Minor
Attachments: loadtest.txt, memory-summary.txt
** I've been testing against the certified branch, last cloned yesterday with certified/13.8-cert1-rc1. It would not allow me to select that as a version however **
While using sipp as a generator to load test Asterisk I've come across a memory leak that very quickly exhausts the host of resources.
The testing methodology is pretty simple: use sipp to launch 1500 concurrent calls to asterisk with a call rate of 25/sec. On the asterisk side use the RAND function to generate two numbers, one of which is the confbridge number and the other (either 0 or 1) is to determine whether to use the moderator profile or participant. The call is then dropped into a ConfBridge for 60s and Hungup.
After a few thousand completed calls the memory usage grows and eventually exhausts the host resources. I recompiled with MALLOC_DEBUG enabled, the output of memory show allocations is attached. It looks like the allocations are in stasis_channels, well after all channels have been disconnected.
