Max. No. Processes/user

Hi All,
I heared that each user in UNIX have max. number of processes that can be running at one time. Is this correct? If yes, how can I know this number and how can I change it.
N.B.: I am using Sun 5.6

Regards

Indeed the kernel has a parameter called something like "Max processes"

Iam not sure how to change hereby the sundoc site, Im sure you can find it there

The file called /etc/sytem is the place to change it.
Iam not sure about the correct syntax

Thank you very much
I will try it...

i know that in linux there is a command called 'ulimit' which can limit many processes and accesses (such as memory).
