Memory Leak
Have a fresh install of FC6 running on a Pentium Celeron 331 (2.6 gHz) with 512mb of memory installed. After a fresh reboot, about 372 of the 512mb are used with about 135mb free. But, the machine steadily loses memory while on. FWIW, I run a lot of process on this machine via cron, both Perl and PHP scripts, numerous times throughout the day. The processes though only last for 2 to 30 seconds, then end. Here's a top output:

As you can see, after about a day of uptime, I've only got 5K free memory. Any ideas what might be not allowing the memory to recycle?
Here is the free output:
