I have a windows 2003 Server SP2 that is a virtual machine sitting on ESX 4.1. There are over 40+ servers in this virtual environment and at any give time 15 servers on one host. For this virtual server, I from time to time receive a "the Instruction at "0x7363b66c" referenced memory at "0x062f8626". The memory cannot be read. I have read some other articles about it possibly being bad memory, but this is a virtual box. The other hosts do not have any issues. Any ideas?
