Subject: Asterisk deadlocks since Kernel 4.1
Date: Tue, 17 Nov 2015 15:46:21 +0100 [thread overview]
Message-ID: <564B3DBD.60500@profihost.ag> (raw)
Hello,
since Upgrading our Asterisk System from Kernel 3.18.17 to 4.1.13 it
deadlocks every few hours (kill -9 is the only thing working). Booting
with 3.18 again let it run smooth again.
An strace shows asterisk is looping like this:
[pid 6068] timerfd_gettime(8, , {it_interval={0, 20000000},

[<ffffffff941d60e9>] poll_schedule_timeout+0x49/0x70

[<ffffffff9463f1ee>] system_call_fastpath+0x12/0x71

Any ideas how to debug this?
