Possible bug in app_swift - Asterisk 11.6-cert4

[bryanburroughs]

I'm not sure how to reproduce this issue but it happens every few days.

Asterisk version: Asterisk 11.6-cert4 built by asterisk @ ivrd02 on a x86_64 running Linux on 2014-08-11 13:55:25 UTC OS: Linux livrp03 2.6.32-431.11.2.el6.x86_64 #1 SMP Mon Mar 3 13:32:45 EST 2014 x86_64 x86_64 x86_64 GNU/Linux

When Asterisk crashes, the backtrace always looks something like the following:

Can you confirm that you're using the latest (github version) of app_swift? I just fixed a little bug that affected asterisk11 in the latest release.

Since I wasn't 100% certain, I download, compiled, and reinstalled last night. Will let you know how it goes. Thanks for the response.

UPDATE: We found the root cause. It is not an app_swift issue but rather security scans were causing the Swift license server to crash, which would eventually cause Asterisk to crash. I'm working with Cepstral support and hoping this can be patched.
