Kevin Harwell commented on ASTERISK-25295:
------------------------------------------

I've been looking into this issue some and like Mark have been unable to reproduce the REGISTER problem. Does the contact uri for the following case actually contain the "=" at the end after "X-PUSH-URI"?
{noformat}
[2015-07-30 12:18:20] VERBOSE[22319] res_pjsip_registrar.c: Added contact 'sip:wiseua at 195.69.202.35:31382;rinstance=e770d0cd5972231a;X-PUSH-URI=
{noformat}
I ask because when copying that line into another editor right after the "=" there is also a non printable character (you can also see it in the verbose log output when looking at the file). If those are added characters then it's likely that a buffer is not being properly NULL terminated or as Mark mentioned the buffer is being used improperly after a failure has occurred.

[~Demon] any luck on getting a REGISTER packet? It would hopefully show us if there is anything odd in the incoming message.

Also you asked:

{quote}
Length important? 
{quote}

It looks like the max length for the contact URI is 256

> Using last git branch 13. Now is 13.5-rc.
> Tired of fighting with deadlock when using chan_sip. Decided to convert all the devices and the gateways to res_pjsip.
> The result was crash very often. When asterisk boots. Sometimes asterisk successfully loaded and crash in a few minutes.
> In the configs, nothing has changed except transfer chan_sip devices to res_pjsip.
