First, install the perl module BSD::Resource
yum install perl-BSD-Resource
Then use it in your program like:
#!/usr/bin/perl
use BSD::Resource;
setrlimit(RLIMIT_VMEM, 1_000_000, 1_000_000);
# rest of the program that is
While having hard limits makes it safer, wouldn't it be better to control the
memory usage of the script instead of setting limits that would trigger an
out of memory...?
How would you control the memory usage of the script if it's run by
the root user?

But what if the program's memory use is dependent on lots of factors
which are not easily predictable.
And you want to avoid bringing the whole system to it's knees while swapping
and killing arbritrary other programs while one program is consuming all
of ram and swap.
In that case it's
I have a perl script which runs from a cron job. How would you limit
the amount of RAM that this script is allowed to consume? Is there a
ulimit setting that will accomplish this? If so does ulimit have to
be run each time the script is run, or is there a way to set it
permanently?

If you run it as a regular user, then maybe you can check out
/etc/security/limits.conf
Currently the script runs as the root user. I may be able to change
this, but wanted to find out whether there was some other way first.
Would it be possible to use a ulimit command within the perl script

Thanks, Paul. I knew I'd find an
