Hi,

Looks like you have a lot of cron processes running at once.

Please could you post the output of this command:
#ps -ef|grep cron|grep -v grep

Also please provide info about HP-UX version and server model.

Rgds.

nothing to worry on this. this is showing your number of cron daemons increased from the maximum number set on your Centralized Monitoring System. You can ignore this alert, these will re-arm, once it back to normal.

It appears there were lots of crontab entries that all fired off at 11:45. Inspect all of the crontab files? Make sure the times are staggered.

Ok, just a one cron process running. Just to check if the lastest "cron/at" comulative patch (PHCO_35331) have been applied in your system:
#swlist -l fileset|grep PHCO_35331

If not is installed, I suggest you applies it.

It is always recommended to have the latest patch level. If you need to apply the patch remember that cron execution will be interrupted during the process can skip the execution of key task. Keep this in mind to use an appropriate time.

Rgds.
