             Summary: Investigate heavy memory utilization by res_pjsip_pubsub
                 Key: ASTERISK-26088
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26088
             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Core/Sorcery, Core/Stasis, Resources/res_pjsip, Resources/res_pjsip_pubsub, Resources/res_pjsip_registrar
    Affects Versions: 13.9.1
            Reporter: Richard Mudgett


Under *heavy* subscribe/unsubscribe load Asterisk will keep consuming memory until the process runs out of memory.

Using a sipp scenario that does the following for each user:
# REGISTER
# SUBSCRIBE to 8 extens
# wait
# unSUBSCRIBE from those extens
# unREGISTER

When simulating a lot of user endpoints the system taskprocessors get backed up.  This can be seen by running CLI "core show taskprocessors" and watching several taskprocessors get backlogged.
