Hi Symm,

Eth3 is connected to our local network and used to manage the SAN, I've unzipped dmesg2 and posted the bottem section below.

Hi enealDC, all of our VMs are very slow at the moment, one is a file server, one exchange, MSSQL etc. I should point out that they had all been running fine before this.

none of the virtual machines seem to be under any extra load, also the statistics page on the SAN shows that network activity over the links to the hosts is about the same during times of poor performance.

Thanks for the help on this guys,
Jon
