We have just updated one of our servers from 6.5.6 to 6.5.8. It is in a VMware inviroment. It will abend any time thru the day or just reboot. However it does it almost every time when we remove a VMware snap shot during working hours when all users are logged in. We opened a case with VMware. We have all the patches for ESX 3.0.2 applied. VMware says it is our SAN's with Netware. We have been running this for over two years in VMware on SP 6. This all happen once we updated to SP 8.

I have attached part of a Abend log

Thanks for the help
Bryan
