Hi All,

We are using SIP over TCP transport but often we got an Asterisk crash with following error.

[Mar 1 11:23:13] WARNING[1509]: chan_sip.c:3755 __sip_xmit: sip_xmit of
0x7f294000cac0 (len 680) to Soft.Phone.IP.Address:56780 returned -2:
Interrupted system call
…. Asterisk uncleanly ending (0). Executing last minute cleanups
== Destroying musiconhold processes
== Manager unregistered action DBGet
== Manager unregistered action DBPut
== Manager unregistered action DBDel
== Manager unregistered action DBDelTree

We have tested this issue with Asterisk 11.20 and it can be reproduced as following

1. From client workstation / labptop register a softphone with Asterisk over TCP
2. Dial into some local asterisk extension. (i.e play voice message in loop
)
3. From client side kill the softphone i.e ( killall zoiper )
4. Wait some time, Asterisk will crash….

Further we are unable to get any coredump ! (even running with -g) Any help will be appreciated.

Thanks in advance

    Interestingly this doesn’t appear as though it’s a crash. Whatever is happening is causing Asterisk to then shutdown normally.

    Please file an issue[1] for this so we can narrow down the problem. I’m not aware of any currently open and I don’t think I’ve seen it.
