Did you find any equipment checks on the VM console? We had a situation were Linux didn't do well at all under equipment checks (some looped, some hung, some crashed).

Our SLES reported the following errors. The two DASD volumes are DEDICATED, we use LVM without striping on ext3 mounted points used by Oracle.

No more hourly cron jobs ran again and no one could log on so we had to reboot after 12 hours of no activity (we did not notice that it was not working, it is a test system). Last night (Jul 26), the system went to 100% CPU again but no dasd_erp messages were reported and cron jobs stopped running. We had to reboot again. Has anybody had any incidents with this type of configuration. I could not find messages on the EMC console. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
