Bug#804652: asterisk: Crash of asterisk with Segfault

[Alexander Gun]

Package: asterisk
Version: 1:11.13.1~dfsg-2+b1
Severity: important

Dear Maintainer,


asterisk crashes once a week with a segfault.

here is a short crash message from dmesg

[3029918.722174] asterisk[30561]: segfault at c9f63ad6 ip 00007f84f2123e2c sp 00007f8487b1c860 error 4 in libc-2.19.so[7f84f20d9000+19f000]
[3874464.510536] asterisk[19998]: segfault at 4cd8d2e5 ip 00007f23c8e78e2c sp 00007f235d952860 error 4 in libc-2.19.so[7f23c8e2e000+19f000]


One side affect is, that you cannot restart asterisk by

> systemctl start asterisk
is not able to restart the process. You have to
> systemctl stop asterisk
> systemctl start asterisk
to get it up again.


The major problem is of course, that asterisk crashes.

I installed the dbg packages and I'm writing a core-dump next time the crash happens.
