Help on System Freeze in SCO


My SCO server freezes suddenly. I just want to know if there any tools / commands availble that can find which is causing the freeze?

Any help on this would be greatly appreciated.

Check first that it really is hung by telneting or sshing from another machine- it may just be the console. Hook up a serialconnection - maybe it's just the nic and the console.

If it really is frozen solid, then hardware is suspect: power supply, scsi termination, scsi cables, motherboard. In the old days, slightly low power from a defective power supply could do this - I don't know if that's still true with modern m/b's.

A kernel call that is completely masked and is stuck in a loop would create a "frozen" machine. That's pretty unlikely.

There are some documented instances of problems/workarounds etc. Look at
The SCO Group, Inc. | Support | SCO Product and Maintenance Download Page to see if you are missing updates or patches.
It would help to know the release number and hardware configuration.

I've seen several failing with power issues. Does your lighting flicker? Are you on a UPS? If so, have you tested to see if the batteries are possibly shot?

Thanks to all with your replies. I will just check if there are any issues with Harware or with UPS.

Is there any monitoring tool or utilities availble to check what might cause this? I came to know there is one open source utility "NAGIOS". Can i use this for SCO 7.1.3?

In bash, grep -v -e '^[[:space:]]*$' filename.txt will filter all the blank lines from filename.txt and display the results.
True or False?
