NEVER clean shared memory or semaphores with the server running!. Having said that. Can you answer the following questions? When at 100% cpu which tasks are consuming CPU? Router? Update? Server? ADMINP? Does the CPU spike occur at certain times of day? How regularly do the CPU spikes occur?

We are now using Domino 6.5.2. Ever since moving to the 810, we've had problems with Domino sucking up system resources and bogging the machine down, even sometimes to the point of needing to IPL (although, for a time, we had a problem with our UPS and that may have solely caused the IPL problems). Anyway, when it has been bogging down, we'll see cpu utilization fly up to near 100% and everything comes to a grinding sloth. We decided to move Domino into its own memory pool, which has helped contain the problem away from stopping other operations, but the problem persists. Our Domino pool size is 1400 (we have 2 Gig total), and the non-DB fault and pages always hover over 150, but jump to 5 or 600 when the thing bogs down. We generally have the max active set to around 300, but spike it up to 600 or so when Domino starts misbehaving and it seems to usually resume processing. I found a post elsewhere about domino on iseries leaving a bunch of junk files in 'Application Development'->"Interprocess Communication"->Kernel Message Queues, Semaphore Sets, and Shared Memory, all belonging to QNotes, and we do have a large number of files in those areas belonging to QNotes. But, I can go through and delete them, even without bouncing the Domino server, save for the ones dated with the current date, etc. Does anyone have any suggestions as to where we can go with this? I hesitate to think we just need more memory - the old 820 only had 1 Gig of ram, whereas we have 2 Gig now, and things ran fine on the 820. I also recently ran a cumulative ptf on V5R2 in case it had some problem that had been recognized and dealt with, but I didn't see any improvement. Also, I looked for a group ptf for Domino 6.5 on V5R2 and didn't see one on IBM's site..... Any and all suggestions would be greatly appreciated! Al Yarrington I.T.
