Perl on freebsd: max memory limit?

[John Bokma]

Is there a max memory limit for a Perl process on freebsd? A script bombs
out when it uses close to 512 MB. (I have no direct access to the machine,
just asking for someone).

Perl itself doesn't have memory limits. However, memory is limited to
what the OS is willing to give to the process. How much memory Perl
can get at most determines on the amount of memory available in total,
the memory used by other processes, and any process limits.

If a 'perl' running on a 32-bit machine can address only 2^32 bytes of
memory, isn't that a memory limit?

(I don't know the architecture of 'perl' - maybe there are type bits
and stuff that make the effective range less.)

(The language Perl probably doesn't stipulate any minimum or maximum
amount of usable memory. Or does it?)

Yes, I was suspecting the OS setting a limit on max memory per process. On
the other hand, the script attempts to slurps a file of over 512 MB (no I
didn't write it ).

You might want to check your ulimits settings.

Thanks, I will pass the information on. In the mean time I "fixed" the
script by not slurping 512 MB, but reading the data when needed. I
suggested a rewrite since the script does a lot of inefficient things.
