Troubleshooting High CPU Utilization on Cisco CSR1000V Series


Hello everybody.

I have some troubles with CPU utilization on a Cisco CSR1000V Series Router. It periodically rises up to 100%. I found out a pair of documents about troubleshooting techniks for this kind of issues. These articles are: Troubleshooting High CPU Utilization on Cisco RoutersTroubleshooting High CPU Utilization. But I think that in the case of CSR1000V those articles are not so usefull and they have not helped me a lot. Mostly because this is a virtual machine that is executed on VMWare, but those articles are for "hardware" Routers.
Can anybody recommend me a good article about troubleshooting high CPU utilization for CSR1000V Series or for a Virtual Router?

P.S.: I tried to find something relative on Cisco-site, but found nothing. Maybe I have overlooked something. If so, please point out it.

Update: Some articles were beign advised to me but there are some small inaccuracies

Update 2:

As a starting point for troubleshooting can be used: Cisco docwiki CSR1000V:Home

Short bursts to 100% are fine.  Are they just short bursts?

Hi, unfortunatelly it is not a short burst. It can last very long time. Last time it last for about 30 minutes until I reloaded it. Previous time it lasted for some hours but I am not sure whether it began working itself or someone reloaded it by hand.

Of course, I opened an SR but they do not hurry. Since the issue arose I am trying to investigate the issue by myself but I was able to find too little information about this type of issues. I tried to find the same issue in the Bug Search Tool, but without any success. Maybe I am trying to find answers in a wrong place.
