What log files to read when OEL 6 VM hung

Hi All

We are trying to determine why our demo system using OEL 6 VM hung on or before Oct 18.

We notice

vang pts/0 dhcp-6ow Thu Oct 18 15:19 - 15:19 (00:00)
rhonrada pts/0 dhcp-pl2 Thu Oct 18 14:31 - 14:31 (00:00)
root pts/1 dhcp-pl2 Thu Oct 18 14:30 - 14:30 (00:00)
reboot system boot 2.6.32-100.28.5. Thu Oct 18 14:29 - 10:56 (6+20:26)
root pts/0 d384.us.texas Tue Oct 16 17:10 - 17:10 (00:00)

According to the log, we found theses errors before the system rebooted:
Oct 18 03:19:03 spos pcscd: winscard.c:309:SCardConnect() Reader E-Gate 0 0 Not Found
Oct 18 03:19:03 spos pcscd: winscard.c:309:SCardConnect() Reader E-Gate 0 0 Not Found

Oct 18 09:20:00 spos kernel: nfs: RPC call returned error 88
Oct 18 15:20:00 spos kernel: nfs: RPC call returned error 88

what do these above errors mean ?

What and where the logs we can see more to determine the root cause of the hung ?

Thanks

    You can generally not conclude the reason for a system crash by analyzing errors that are most likely follow up symptoms. If the history of the /var/log/messages syslog file does not provide any real clues and the machine has reset instantaneously, then the machine most likely reset due to an external problem. External problems can be associated with power failure, hardware, firmware or heat issue, or problem with your VM solution. The kernel provides mechanism to further analyze a system crash, e.g. Kdump, but then it depends on the source of the issue. I'm afraid the possibilities and options to troubleshoot are far to complex to be discussed here. As far as I'm aware, there is no usable information in your post that can pinpoint the problem.
