Likely this is the <b>ulimit</b> or actual kernel resource rather than perl.

You can easily create a while loop that { push @foo, rand(); } and run out of memory. Testing for memory used is sort of tricky depending on perspective, but perlmonks has plenty of threads on it.

NAME
smd-loop - iterates smd-pull and smd-push SYNOPSIS
smd-loop [-vt] DESCRIPTION
smd-loop runs smd-push and smd-pull at regular intervals as defined by the user in the ~/.smd/loop configuration file. On errors that are reported to be transient, it retries a second time before failing. The configuration file is line-oriented. Each line is composed of three space separated fields: pull-frequency, push-frequency and end- point-name. Frequencies are expressed in minutes, while endpoint name is a valid name for smd-pull(1) and smd-push(1). Lines beginning with # are considered as comments. The following example calls the command smd-pull default every 3 minutes, and smd-push default every 10. Example: # pull-frequency push-frequency endpoint-name 3 10 default OPTIONS
-v Increase program verbosity (printed on stderr) -t Just create a template configuration file if none FILES
