Hi!
I got VMware Server 1.0.5 build-80187 installed on HP ML570 G4 (4 quad-core Intel processors, 16 GB RAM, Windows Server 2003 R2 Enteprise Edition, SP2 ). It also is fileserver and MS SQL server. Usually it is minimally loaded. 2 VMs run on this host system - FreeBSD 6.2 with 256 MB of RAM and Windows Server 2003 Enterprise Edition SP2 (acts as terminal server) with 3 GB RAM. Host system reboots under heavy disk load. Ususally it happens during backup\restore sessions. First system cache (I can see in Task Manager) grows to 12-13 GB. Then if someone connects to terminal server, host system reboots. Or it may work for some time and then it reboots. If I start restore session just after booting host, it usually reboots after restoring 10-15 GB.
I tried to disable memory trimming, to play with memory reservation amount - no significant changes. First I saw such behavior on 1.0.4 , then I upgraded to 1.0.5 and upgraded VMware Tools on guests. No significant changes.
I wonder is it VMware problem or is it Windows problem? May be there is the way to tune system cache on host system?
