[asterisk-bugs] [JIRA] (ASTERISK-29137) pjsip: Broken pipe when sending requests

[Luke Escude (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=261295#comment-261295 ] 

Luke Escude commented on ASTERISK-29137:
----------------------------------------

This appears to have happened again, but I have new info. Log filled up with these:

[Feb  3 17:57:31] ERROR[10738]: res_pjsip.c:1579 endpt_send_request: Error 120032 'Broken pipe' sending OPTIONS request to endpoint (SIP PROXY ADDRESS)

This is on Asterisk 16.30.

The interesting thing is that this particular customer was NOT using TCP - They've been switched over to our new UDP-only proxies. So, the whole tcp issue seems to be more of a symptom.

In this case, ALL  sip processing stopped - UDP, TCP, didn't matter which. This customer is pretty high-volume, so maybe there's some limit to pjsip that we're hitting over time.

> Currently I am fixing a small bug in our proxies that causes Asterisk to add a x-ast-orig-host parameter to contacts... Could that cause something like this?
> The transport is TCP for all communications.
