New Server rebooting at an irregular interval, running x64 OS and

We have new 64-bit server and SQL Server 2005 where we moved databases and

applications from a 32-bit server and SQL Server 2000. Since we have moved

the databases and application to the new server the server crashes and

reboots at an irregular interval. This reboot seems to always be proceeded

by the memory working set for SQL Server being paged out and available memory

going up by a large amount. This usually occurs hours before the server

crashes. The available memory stays high until the server crashes.

OS: Server 2003 Standard edition x64 Edition

Version 5.2.3790 Service Pack 2 Build 3790

Hardware: HP ProLiant DL380 G5 with two Dual core cpu's 3000 MHz.

4 GB of memory

SQL Server Standard Edition (64-bit) Version: 9.00.3054.00

Using the performance monitory we can see the memory event that proceeds the

reboot and have ruled out some likely candidates like the Anti-virus and

backup software. The reboots occur anywhere from less the 24 hours apart to

4 days.

Does anyone know of any problems with SQL Server Standard x64 and memory

problems?

Any suggestions on how to identify if SQL Server is the problem or help

identifying some other service or driver as the cause of this problem?
