Hi Members of the Support Forum,
i post this here and not at the Bugs section - because iam not realy sure we are talking about a bug or some missconfiguration on our side.
We are using OpenVz since some weeks and have random crashes of the hole machine. We made sure that the hardware is not the cause by moving all the stuff to a different server (same hardware config though).
Now we are sure now that it is not a memory or cpu failure. But it could still be some kind of conflict between some harware components and the VZKernel ...?
There are no debug messages in the syslog that are of any use ...
When the mashine crashes it is still possible to ping it for a while. After that it is not even possible to ping it any more.
We had to change the beancounters very much - otherwise we were getting errors about open,files etc, (see further down)
The crash seems to occour when load goes up. Any Ideas where we should start to search? Monitoring the beancounters did not give us a hint.
At the moment we definitly cant use the system for production ...
Very strange all together ...
Thanks
Christian
