             Summary: Receive OPTIONS message, sometimes cannot send response "Unable to send response (-1)"
                 Key: ASTERISK-30342
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30342
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip
    Affects Versions: 18.15.1, 18.15.0
         Environment: Ubuntu 20
            Reporter: Dan Cropp
         Attachments: debug_log, messages, pjsip.conf

We have two Asterisk VMs front ended by a Kamailio box.
Kamailio sends OPTIONS messages to Asterisk to determine if it's still alive.
Whichever one has been alive for the longest, is treated as the active Asterisk.

Everything has been working awesome when running Asterisk 18.12.1.
Yesterday, we upgraded the boxes to Asterisk 18.15.0 and started seeing some Asterisk unable to send responses to the OPTIONS messages from Kamailio.  It seems to only happen for a period of time, then it suddenly starts working.

It appears as though the OPTIONS message is processed correctly, but when it attempts to send the response it fails.

ERROR[1281] res_pjsip/pjsip_options.c: Unable to send response (-1)

What is really strange is that after a period of time, it suddenly is able to successfully send responses to OPTIONS messages from Kamailio.

If we then change the configurations and tell asterisk reload, the same issue repeats.
