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 Nasir Iqbal ICTBroadcast - an Auto Dialer software for ITSPSMS, Fax and Voice broadcasting & Inbound / Outbound Campaigns http://www.ictbroadcast.com/

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.
