Ticket #8631 (closed defect: fixed)
Large page allocation times out - causes guest hang

On a host currently running 11 guests (mixed linux and windows), one of the Debian 5 64-bit Linux guests quickly freeze up as soon as it starts running its batch jobs (CPU intensive and NFS I/O intensive).
The last message in the log file before the freeze is:
00:00:51.020 PGMR3PhysAllocateLargePage: allocating large pages takes too long (last attempt 3960 ms; nr of timeouts 2); DISABLE
The host system processors are only utilized some 11-20% while all this is happening. Also, vmstat reports a 7.5GB free list.
Attaching to the VM console never results in an updated console window - I get the RDP window, but the contents of it never update.
Worse yet... When I attempt to power off the VM using VBoxMange controlvm poweroff, The poweroff hangs before 30%:
$ VBoxManage controlvm sparrow.rd.evalesco.com poweroff 0%...10%...20%...
After several minutes, I try to kill the VBoxHeadless process that is hanging. This causes VBoxManage showvminfo to hang for the VM, but the process does not go away.
A kill -9 is not effective either. The process lives until I reboot the system.
