We are currently running about 120 Linux instances on our 1 IFL G5 with 1.5G storage.
After I added about the 100th Linux, VM began refusing to dispatch some of them for extremely long periods of time (hours). If I re-IPL VM and start all 120 Linux systems up again it runs fine for a couple days, then the problem starts occurring again. I Think a VM resource is being over committed or something, so VM just decides it doesn't have the resource to run some of them anymore so it puts them on the eligible list, but, never dispatches them again or at least not until a resource becomes available again which could be hours later.

There seems to be plenty of CPU available and paging is light. Anyone got an idea what might be causing VM to not dispatch these users? _____________________________________ Lonny Sivey System Support Division OCLC Online Computer Library Center, Inc. 6565 Frantz Rd, Dublin, OH 43017 (614) 764-6013 FAX (614) 718-7200 mailto:[EMAIL PROTECTED] _____________________________________
