Amount of swap/virtual memory a process is allowed to use

[pneely]

I'm running Solaris 2.5.1 on Ultra II's with 1gb of RAM and 1.5Gb of swap. I'm wondering if there is a setting/configuration that would set the amount of swap a process is allowed to use or is that all handled by the program/application ?

You can limit the memory a process can use (via ulimit), which would indirectly limit the swap space.

Thanks....
So, if I wanted to limit the amount of swap "all" processes can use down to 400mb I would use;
ulimit -v 400000 (in kbytes)

Can it be set for only certain processes that are giving us problems...(memory leaks) ?

I'm not aware of any way to do this by process... processes inherit this from the parent shell. You could write a wrapper shell for a specific process that sets ulimit within the wrapper.
