i am experiencing memory problems trying to run an application that processes
a file of about .5GB. So far my results are:
(1) set ulimit as follows:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) 256000
max memory size (kbytes, -m) 256000
open files (-n) 1024
pipe size (512 bytes, -p) 8
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) unlimited
virtual memory (kbytes, -v) 768000
This gives me 'out of memory' errors.
(2) set 'virtual memory' very high and the application hogs memory and brings
the rest of the system to almost a halt.
Thanks in advance for any help you can give me,

Hi, Tom:
I don't know anything about 'ulimit', but how much real memory do you have?
I'd try adding another 2 Gigabytes of virtual memory.
Also, try
nice -n 19 <application>
so that it does not 'hog' the system so much.
Run 'top' to watch how much memory your application uses.
HTH, Chuck
