I've seen this happen due to scsi bus resets caused by a flacky disk/controller. Just food for thought.

BTW, you are running this many instances in only 4GB? They must be really really small or you are hitting swap pertty hard.

Thanks,
Ron.

We have a development box that is HP-UX B.11.11 9000/800. It has 4gb of memory. It is running anywhere from 5 to 7 8i instances and 3-5 9i instances on any particular day. Once every week it will "lock up". vmstat will show blocked processes and the %wio will go to the high 90s. Nothing crashes or dies, it just appears to have to many processes to run. I have used TOP to look at the processes running. I see nothing unusual. Can anybody share their kernal parameters for HP that they have running 8i and 9i on? Particularly the shmmax, shmmni, ... and so on. Any help will be greatly appreciated.
