             Summary: Possible Memory Leak in PJSIP TLS Transport
                 Key: ASTERISK-29274
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29274
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 16.8.0
         Environment: Asterisk 16.8-cert5 using pjproject-2.9 on Gentoo on QEMU KVM
            Reporter: Troy Bowman
            Severity: Major


Last Saturday morning, I enabled the TLS transport in my PJSIP configuration and turned on SIPS for our Polycom phones and our provider trunks. I wanted to test TLS while we have a lower weekend call volume. 
 Things worked well, aside from some non-fatal errors. However, I am concerned that memory usage gradually increases with this change.

Please see my community post for graphs and the steps I took to find out what was filling up memory unnecessarily:

https://community.asterisk.org/t/pjsip-tls-transport-memory-leak/87363

I have since disabled TLS on all of my Polycom phones and trunks, and it is behaving normally as it did before.  TLS is the only difference in this change, so I am pretty sure there is an issue with the storage of client certificates and CA certificates.

I can provide one of the 128M memory page dumps by other means if it is desired.
