Re: [cisco-voip] VMware 5.5
I had a CPU pegging issue about 4.5 months ago on ESXi 5.0. I turned LRO off (only change I made), and I haven't had an issue with CPU pegging since. My issue was due to the TCP throughput being irregular on VMXNET2 and VMXNET3 and it was causing HELLO/ACK issues with the database replication (it would get into a setup loop and never stop). Guest reboots didn't fix it, if a rebooted the UCS box it worked for a little bit and then went right back to the issue VMware states that the issue is known in Linux kernel 2.6.24 and later with VMXNET3 (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1027511) There are plenty of reports on the Internet were the LRO/CUC issue has been found beyond esxi 4.1 and cucm 8.6. RHEL probably isn't going to get any performance gains from LRO anyhow so if it were me, I'd turn it off. It's broke now, right? Generally, you can't break broke so I would try it, if for no other reason than to say that isn't it. Again, I am not saying this IS your issue, just that it COULD BE a contributing factor, it would be worth a shot in my book if you haven't found the issue yet.
