Hi,
During the last weeks my primary HN have crashed a few times.

Netconsole Reports = None

Logs = None

Load Average > 300 (Dual Core CPU)

[root@vps1 ~]# vzmemcheck
Output values in %
LowMem LowMem RAM MemSwap MemSwap Alloc Alloc Alloc
util commit util util commit util commit limit
2.75 33.63 20.99 6.79 22.86 15.58 22.33 48.34
[root@vps1 ~]# vzcpucheck
Current CPU utilization: 132684
Power of the node: 228284

CPU Limit (50 per VPS)
All config files are checked by verify utillity and are valid.

Since there are no logs i'm unable to trace the problem, anyone have suggestions?

Thanks in advance,

Hello,

What kernel do you use?
Is it possible for you to attach serial console to the node in question?
Have you tested hardware? (http://wiki.openvz.org/Hardware_testing)

Thanks,
Vasily.

I'm using the latest stable kernel 2.6.9-023stab037.3-smp

Netconsole is completly empty

And hardware passed in all tests (CPU, mem)

I'd reccomend to setup serail console and increase console log level to maximum ( i.e. 'echo "8 1 4 8" > /proc/sys/kernel/printk').
Netconsole is less reliable, than serial one. If it is impossible, even monitor output photo will be usefull. Without info we can do nothing.

Since i'm unable to find the problem i'm going to reload the box, now when i tried to migrate the VE's i get the following:

Starting online migration of VE 109 on 10.0.0.28
OpenVZ is running...
Preparing remote node
Initializing remote quota
Syncing private
Live migrating VE
Setting up checkpoint...
Error: No checkpointing support, unable to open /proc/cpt: No such file or directory
Failed to suspend VE

[root@vps1 /]# modprobe vzrst
[root@vps1 /]# modprobe vzcpt
[root@vps1 /]# uname -a
Linux inf1 2.6.9-023stab037.3-smp #1 SMP Wed Dec 13 19:31:35 MSK 2006 x86_64 x86_64 x86_64 GNU/Linux

Shouldn't vzctp be available?
