AFW_application_ and 100% CPU load

[sogazmvgg]

I have C2911 with loading c2900-universalk9_npe-mz.SPA.152-4.M5.bin

(but with previous releases situation was same )

I use ССM Version 9.1. in my bundle. I have native phones (6921, 7962) and several SIP DLink gateways. ISP interconnection by SIP.

I have IVR on it, but when I stoped IVR  - situation was same.

In random time moment

CPU utilization for five seconds: 99%/0%; one minute: 99%; five minutes: 99%

PID Runtime(ms)     Invoked      uSecs   5Sec   1Min   5Min TTY Process

177     2034368       15814     128643 98.61% 97.98% 97.89%   0 AFW_application_

and all calls rejected -  AFW_application hungs up.

Problem was found. There was one loop in voice-hunt group. Last number point to pilot number.

So after some loops - 100% AFW_application_

Had the exact scenario with AFW_application_ eating 100% CPU.  Checked my hunt groups and I had a loop.

voice hunt-group 1 parallel
 phone-display
 list 3400,3401,3402,3403
 timeout 30
 pilot 3400

Thanks!
