PGMPOOLKIND_FREE Assertion

[Costin Grigoras]

After a couple of weeks of running I got this exception:

!!R0-Assertion Failed!!
Expression: pPage && pPage->enmKind != PGMPOOLKIND_FREE

The interesting thing is that your host processor is quite fast but the log file contains a lot of complaints that ATA commands took a long time to complain. Though this shouldn't be related to the PGMPOOLKIND_FREE assertion...

[Costin Grigoras]

Yes, we had quite poor hard drives (5400 RPM) that even in RAID 5 of 4 of them were performing bad. The guests were also crashing from time to time complaining about IO errors, FS was remounted r/o ... all kind of crap. We have assumed they were caused by the poor IO so we've replaced the disks recently. If we see the errors again we'll come back with bug reports.

another occurence on a a Mac (added by jeyrich)

I have added a log file for a similar occurence on a Mac Pro. It happened on the first day of installing VBox, though. Could disabling Nested Paging and/or Hardware Virtualization help to circumvent the problem for now?

[jeyrich]

Oh, and I found this in system.log after the crash

Notebook:

This guru meditation failure has just occured on my Ubuntu XPS M1530 running Ubuntu Jaunty Beta and VirtualBox 2.

Drive:

I have a Vertex SSD Drive from OCZ running EXT 4.

Suspected Problem:

I suspect it may be a ssd drive firmware issue as some of my colleges have been reporting a few problems. Im logging this in case it is not or maybe an EXT 4 problem or something else.

Log:

Experienced PGMPOOLKIND_FREE Assertions for two Solaris 10u6 guests running concurrently (VBox-vm1.log & VBox-vm2.log attached) running on the same Ubuntu Linux host with Virtualbox 2.2. One of the Solaris 10u6 guests was performing a code build at the time (VBox-vm2.log) so there would have been a fair amount of I/O and CPU load.

This is the second occurrence of PGMPOOLKIND_FREE causing the two VM's to crash in two days.

EXT3 used as the host file-system.

The two remaining guest VM's (one Solaris 10u6 and the other a Redhat 4 EL guest) are still running fine.

[Frank Mehnert]

This problem should be actually fixed with VirtualBox 2.2.2. Please reopen if this problem still occurs with VirtualBox 2.2.2.
