High Core Switch CPU usage when running MSSQL backup
My Network guys are complaining of high CPU utilisation on a Cisco 6509 core switch when we kick off our MS SQL backups from one of our SQL clusters.
Client is Windows 2008 R2 running 18.104.22.168 using the MS SQL agent going to a 5220 running 22.214.171.124.
We are using a dedicated backup network and the IP's he is giving me from the log match the above pair.
The process causing the CPU spike is a "Virtual Exec" process.
Has anybody seen anything like this ?
Google hits seem to point to issues on the switch, but as usual NBU is getting the blame.
Any help would be appreciated.
Thanks - Darren
