Hi everybody,
We had a really strange issue last night on our esx infrastructure :
We noticed that some of our VM went down and being not accessible so we start looking at ESX host and saw that one of them was down.
After long hours of diagnostic, we saw that one port of our main switch was doing broadcast storm so we unpluged it and restart our ESX and everything went fine again.
On our vCenter, we had lot of alerts saying that some VM's were unreachable and also CPU alert temperature on host.
On the ESX console, we saw that there were a purple screen (no screenshot badly) but it was talking about CPU Locked up !
My question is: why a broadcast storm situation is crashing our ESXs ?
We have 3 ESXi (5.1.0 build 799733) on HP Proliant DL360 G7 and a HP MSA Storage P2000.
Does anyone have any ideas or used to have same situation ?
Thanks a lot
Best
Nic.
