Error when a connection is gone

[ma-hack]

Hi, i found a issue when the callmanger reboots and gets up again. After that i get the connection setup failed message with Timer allready cancelled. After that the sip is completly broken. I was not able to fix it. Have you maybe an idea how this can be fixed?

2016-09-18 15:55:38,404 ERROR [Thread-673] (SipProvider.java:755) - connection setup FAILED: java.lang.IllegalStateException: Timer already cancelled. 2016-09-18 15:57:39,343 ERROR [Thread-673] (SipProvider.java:755) - connection setup FAILED: java.lang.IllegalStateException: Timer already cancelled. 2016-09-18 15:59:39,452 ERROR [Thread-673] (SipProvider.java:755) - connection setup FAILED: java.lang.IllegalStateException: Timer already cancelled. 2016-09-18 16:01:41,998 ERROR [Thread-673] (SipProvider.java:755) - connection setup FAILED: java.lang.IllegalStateException: Timer already cancelled. 2016-09-18 16:03:42,100 ERROR [Thread-673] (SipProvider.java:755) - connection setup FAILED: java.lang.IllegalStateException: Timer already cancelled.

it does not terminate the connection when tcp_conn is null
