I am kind of new to linux kernel (not totally new) but the issue I am facing on my linux is that the machine hangs and I dont have much clue on this. I get to see these messages in my /var/log/messages file and I need some pointers on where the issue could be and because of what ? Linux kernel is 2.6.18-128. For detail, please see the attached file. Thanks in adv.

Any more info on when this happens ? Does it happen when you boot, or while running a certain program, or at random, etc ? It is important to know when it happens and if it is consistent or random.

As a general recommendation for hangs like this, I would run memtest86.

H_TeXMeX_H: read log again! It cannot happen on boot, as there is info about java - java isn't called anywhere close to boot time.
