Description:Many message of "bad magic number" appears and after asterisk stops automatically (or restart if I use safe_asterisk). Last time, appeared more then 400 times (about 10 per second).

The message is:
[Feb 10 08:41:32] ERROR[29506] astobj2.c: bad magic number for object 0xb6e9a728. Object is likely destroyed.

or, sometimes:
[Feb 10 08:41:34] ERROR[29506] astobj2.c: bad magic number 0x4d584157 for object 0xb6e9a728

I dont know exactly how to reproduce this error. But it happens ~5 times per week.
I tried to change version, but same error happened.

On that server have about 92 SIP peers and more 100 analogic peers (Khomp device).

Attached are complete logs and gdb file.

Per the Asterisk versions page [1], the maintenance (bug fix) support for the Asterisk branch you are using has ended. For continued maintenance support please move to a supported branch of Asterisk. After testing with a supported branch, if you find this problem has not been resolved, please open a new issue against the latest version of that Asterisk branch.

Thanks!
