RTM Message IpVms

Hi.

Real Time Monitor has reported Alert kernel: IpVms: StreamMixer: Excessive mixer calls, Does anyone understand what this means as Google and CCO has not thrown any light on this? Should I be concerned?

Cheers

Richard

Hi Richard,

Please check bug id:

CSCte19629    "Excessive  mixer calls" alerts from IPVms

Symptom:
IpVms media driver issues error to system log "Excessive mixer calls"

Conditions:
Other (unknown) system processes are causing the kipvmsMixer## process to
not be scheduled for execution for a period exceeding 100ms.  Since
kipvmsMixer## process is running at high priority (near RT) about the only
other processes that can interfere are system / kernel related.

Side-effect of this is the audio media being streamed from Media Streaming App
may have jitter issues at the end-points.  With no control over scheduling,
the application cannot do anything to reduce this.  Only possibly by reducing
work-load on the server (number of registered devices or call traffic).

Workaround:
Ignore the error message.

I hope this clarifies your question.

Regards,

Tere.
