I am currently running Ubuntu 14.04 LTS (fresh install) on a Dell Precision 7910. When I attempt to do any heavy analysis (ie. processing 4-10 large files at one time), the machine completely freezes. Neither the mouse nor keyboard respond, and I end up doing a hard reboot. ALT + PrtScn + R E I S U B did not do anything.
I looked at the log files, but there is nothing there from the time of the freeze.
Although I am quickly able to reproduce this problem running a particular java program called GATK, I have also run into it while running C programs. Sometimes it freezes right away, and other times it takes 20-30 minutes.
The Dell ePSA diagnostics test and memtest86+ test both passed.
Can anyone provide a step-by-step way to figure out what may be causing the system to freeze?
Thanks for your help! RC
