I don't think just a system call would be the culprit. If the system
call is not returning, or if something is leaking memory, then that
might certainly be the culprit.
I'm not sure if you maintain the code in question, but shelling out to
do something like a copy is really expensive and inefficient. You could
replace it with just perl code to just read in the file and output the
contents to the destination file. This should help performance because
the system does not have to fork, set up the shell, execute the 'cp'
program, and then return.
