ulimit and 64 bits process

tommy_cs · #1 (**permalink**) 11-15-2007

as we know, ulimit can be used to limit the stack and heap size of a process occupy. However, the space for 32-bits and 64 bits process are different.

for example, "ulimit -s xxxx" only limit the stack size of 32- bits process, am I right?

How to limit the size of 64-bits process?

thanks a lot!

Thanks!

if it is on Red hat linux, how we set the stack size limit for 64 bits process?
can we still use ulimit to set the limit?

Thanks!

Re max stack size on HP-UX 11.23, have a look at the kernel parameters - maxssiz and maxssiz_64bit:

so ulimit is no use on HP-UX?
