Re: memory error in my root log file
Looks like Memory DIMMS are having an issue.
Log a case with HP support/Response Center for a confirm check.
Also, use STM for memory errors.

Re: memory error in my root log file
You should call HP and have them check your RAM. You have at least 1 DIMM that probably needs to be replaced.

Re: memory error in my root log file
Try
echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm
to get some details, but obviously you have a problem with bad memory.
Ask support for analyzing and replacement.
Hope this helps!
Regards
Torsten.

Re: memory error in my root log file
your RAM/DIMM in slot 1b is defect.
As told in your log file, the os can correct a number of memory errors (256).
You have 241 different errors now.
If you get more than 256, your ws can hang up.
So if you need a high availability you should change this DIMM soon.
If you don't have a support contract, you also can lower your RAM from 4GB to 3GB - remove the DIMMs in slot 1b and 1a and move DIMMs from 2a/b to 1a/b.

Re: memory error in my root log file
EMS events are great because they are very detailed. I (we) suggest following the Recommended Action and check memory, that error is an HW problem about memory and you should open a call by HP asap.
Best regards,
