process memory allocation

by Jiong Wan » Mon, 08 May 2000 04:00:00

Hi,

Does any unix guru out there know how to change the memory allocation
limit for a process? We are using a sun solaris machine, and once a
process get over 250MB, it complains about out of memory even though we
have 512MB physical memory.

Thanks very much,

Jiong

1. Process/Memory Allocation Problems

Hey,

I've got a serious problem with a database application (AceDB) on a
SS10/Sol2.4 with 32Mb. Whenever one of my users starts doing any
serious searching or works with a big data-set the program dumps with a
memory allocation error and tells me it can't create any new processes.

No problemo, says I, and I start tweeking up maxusers. Problem is, no
matter how high I set maxusers, max_nprocs, and/or maxuprc the thing
still crashes. I've also tried playing with lotsfree to open up more
pages to no avail. The same app runs like a dream on a SS20/Sol2.5 with
64Mb without needing any plugs in /etc/system.

Is there something stupid I'm over-looking here? Any help greatly
appreciated.

Thanks!
Dan.
