You could possibly try checking you don't create any circular references,
i.e. parts of your hash which refer to other parts of your hash.
Also if you have finished using a hash you could try $hash=();
And finally, try to ensure you don't use global hashes. If you use local
hashes then perl's memory recycling should kick in when the hashes go 'out
of scope'.
However I have also had simillar problems with memory leakage and perl and
currently I believe the general concensus of opion is that the only real
solution is to work out how quickly your programme gets too large and then
have it rexec itself.
Usually if it's a daemon script you have a parent process which continually
checks if your perl script is running, if it isn't it'll start it running.
This way all your perl script has to do is work out how long to remain alive
for and then gracefully exit. Your parent script will then spawn another
fresh copy.
Another option I just thought of is you could use Tied hashes, i.e. hashes
which are tied to a file, rather than memory, could give your script a
greater life expectancy,
