  This doesn’t ring a bell on any issues filed or any posts anywhere. Getting a backtrace[1] would show precisely where it is hanging though. Is it possible a host is having DNS issues? That can cause chan_sip to lock up for a period of time.

• Hi 
  This happens to me when one peer (provider) is bad !Try to remove all peers from your sip.conf and gradually add them back!

  Subject: [asterisk-users] Asterisk 13.11.2, 13.11.1, 13.10.0 and certified-13.8-cert3 : freeze on ‘sip reload’

  Hello

  I am experiencing a freeze of the Asterisk proces when issuing a ‘sip reload’.

  I have this issue every time on asterisk versions : 13.11.2, 13.11.1, 13.10.0 and certified-13.8-cert3.

  I do not have this on versions certified-13.8-cert2, certified-13.8-cert1 and asterisk 1.8.32.3.

  The only solution is a cold restart of Asterisk.

  I can execute any command on CLI except ‘sip reload’.

  This is what I have on CLI :

  sip5*CLI> sip reload
  [Oct  7 23:58:40]  Reloading SIP
  [Oct  7 23:58:40]   == Parsing ‘/etc/asterisk/sip.conf’: Found
  [Oct  7 23:58:40]   == Parsing ‘/etc/asterisk/sipTemplates.conf’: Found
  [Oct  7 23:58:40]   == Parsing ‘/etc/asterisk/users.conf’: Found
  [Oct  7 23:58:40]   == Using SIP TOS bits 96
  [Oct  7 23:58:40]   == Using SIP CoS mark 3
  [Oct  7 23:58:40]   == TLS/SSL ECDH initialized (secp256r1), faster PFS cipher-suites enabled
  [Oct  7 23:58:40]   == TLS/SSL certificate ok

  –> no more output on CLI. Asterisk has gone completely !

  Another ‘sip reload’ gives :

  sip5*CLI> sip reload
  [Oct  8 00:01:10] Previous SIP reload not yet done

  sip5*CLI> sip reload sip5*CLI>

  Other commands are no problem on the CLI (while the freeze occurs ! ) :

  sip5*CLI> core show  version Asterisk certified/13.8-cert3 built by root @ sip5.mydomain.tld on a x86_64 running Linux on 2016-10-07 21:27:15 UTC

• Hello Edilson

  I have removed all sip peer definition in sip.conf.

  I only have rtcachefriends=yes for my mysql realtime sip peers (IP-phones).

  But what I don’t understand is why I have no issue when for example using asterisk 1.8.32.3 again.

  Kind regards.

• Hi Jonas!

  Do you currently use any TLS technology in your Asterisk? Like SIP-TLS o pjSIP-TLS support ? If don’t, please go to modules.conf and start disabling some modules that you don’t use.

  For example, I can see some other modules related to calendars. If you don’t use this, please disable it. You gain a lower memory footprint, and maybe fix your issue.

  I hope this help you. Cheers.
