ESXi 3.5.0 Update 4 Host Disconnects
I've run into a problem on ESXi 3.5.0 Update 4 where the ESX host will disconnect, and then shortly after the VMs will stop responding on the network. If you catch the ESXi host fast enough and get to the unsupported console this command can get you back up and running quickly:
#> /sbin/services.sh restart
It appears that this problem is caused by the CIM providers ( they show the health status for fans, firmware revisions of the storage controller etc ) and what has been reported as a memory leak in the sfcbd process. You can disable these CIM providers by tweaking the Misc.CimEnabled setting from a '1' to a '0' in the advanced properties shown below.
After you change that setting, you'll need to either reboot the ESXi host, or head back to the command line and restart the sfcbd process:
#> /etc/init.d/sfcbd-watchdog stop
It's unconfirmed at this point, but is believed to be a problem that only affects those of you (me) that use Emulex HBAs.
