Hi Den:

Thanks for responding and your patience in working on this. I will try to answer your questions, and also attach a copy of a full kernel dump.

1) Can I try Kirill's latest version?
A) I downloaded and installed his version (ovzkernel-PAE-2.6.18-8.1.8.el5.028stab039.1.i686.rpm
ovzkernel-PAE-devel-2.6.18-8.1.8.el5.028stab039.1.i686.rpm
), but they still failed.

2) I have tries this on 2 differen't VE's. Both of them are based on CentOS 5.0. One of these was the download from the OpenVZ website, the other from my own conversion of CentOS4 to CentOS5.

3) Do I have the crashes on the same node, or arbitrary ones?
I have this configuration running on 6 nodes, and I can reproduce the failure on all 6 of them.

4) Is there any specific activity before the crash?
Nothing special. Basically, I start the host, and than have been using a script to start the VPS, perform a pwd of an automounted NFS filesystem, and then stop the VPS. I can tell it will fail, when the VPS does not shut down completly (vzlist -a shows it is running but has 0 processes). Once in this state (where the VPS does not shut down completely), it takes a while (anywhere from minutes to hours) before the kernel panics. During this interval, I do receive messages on the console, (nfs) "server xxx not responding, still trying"

Here is the copy of the kernel dump. Note, this was run against Kirill's kernel, with out the included patch. I will next work on building Kirill's kernel with the new patch.

thanks,

Paul
