I have Ubuntu 11.04 running kernel 2.6.38-8-server. It is used as vmware-server. It worked for 1 month with no problem. But yesterday it got frozen 2 times in few hours with these messages in syslog:

Can please anyone take a look at it and give me some answer why is this happening as I even don't know what to look for and what to possible change to stop happening any time soon. As I am expecting that another freeze is coming up soon.
