High CPU utilization in voice gateways

[Manickam Ramanathan]

High CPU utilization during non-peak hours in all the gateways. Process-http core is utilizing more CPU and it reaches to 99% and after sometime it automatically resolved and sometimes reload solves the issue. We are using contact centre and back office calls. Any reason why this is happening? IOS version- 15.0(1)M9

sh proc cpu sort

HTTP CORE process is utilizing 99% CPU in sh process CPU sorted.

Hi Tagir,

We don't have ip http server and ip http secure-server command in our gateways.

No connections for the sh ip http client connections.

Please advice what could be the cause of the issue and also note that this is happening only in the late night when there is less call volume/no calls to the gateway.

Thanks...
