Hello,

do you have a possibility to install something similar to serial console in order to collect full output?
http://wiki.openvz.org/Remote_console_setup
It is not clear yet if a provided output points to an initial problem or it is just a consequence of another phenomenon. Moreover , this output is not complete.

I'd recommend you to use memtest86. Have you tried it?
And of course, don't hesitate to file a bug into bugzilla.

Hi,

> yes i make ram test with memtest ,memhog ..
Could you please clarify a bit: did you try exactly 'memtest86' or some other memtester? 'memtest86' is highly appreciated because it runs bare metal, without any OS loaded and thus can check ALL the memory unlike other userspace memory testers.

Thank you.
