- Yes. The two most common limits on memory are:
-
- 1. Having sufficient page/swap space for the amount of virtual
- memory desired.
- 2. Per-process limits for stack and data space. These limits are
- determined from the values of maxdsiz (data), maxssiz (stack)
- and maxtsiz (text) in the kernel configuration file. You can
- check the "Guide to System Configuration File Maintenance" for
- the defaults. The C-shell enforces it's own limits and these
- can be examined with the shell built-in "limit". All it really
- limits is the stack size, because the data size limit defaults
- to the system limit.
