    I have a WRT54GL ver1.1 and was running DD-WRT v24 for IP assigning and Qos; recently this has become unstable so I thought I'd give Tomato 1.21 a try. So far I notice Qos works much better.

    I have 'bandwidth monitoring' enabled and 'Count cache memory as free memory' enabled in debugging.

    My total and free memory reads as follow, is this normal?
    Total / Free Memory 14.19 MB / 6,508.00 KB (44.80%)

    Is there a Cron job script that I can run to clear the memory overnight?

    Clear what memory? It's in use.

    If you want to stay with ALL the memory free, keep the router unplugged. :biggrin:

    Your numbers are normal. There is no reason to clear the memory. If you have stability problems (very few do under tomato), you may want to schedule a reboot.

    My router's been up for 65 days at the moment (no reboots). I still have 6620kB free (45.57%), and I've never "cleared" the memory. It just works.

    You worry too much...

    Your "Total / Free Memory" figures seem to be normal. And there is really nothing you could do about it, except from rebooting your router maybe. But 6,508 kB is quite a lot of memory. That is absolutely nothing to worry about.

    What version of Tomato? I too have found that 1.19 would stay up for months, but 1.21...not so much so. I have yet to clear two weeks. I also wonder if a subtle memory leak isn't to blame, but I've yet to find concrete evidence of it.

    Before my Buffalo took a dump mine was up for nearly 1 month since the last settings reboot. I have not found any problems with 1.21. Let's see how it does on the Asus

    As of now since I loaded Tomato this morning: Total / Free Memory 29.98 MB / 21.66 MB (72.23%)

    I'm running 1.18 now. I jumped in way back at 1.07, and NEVER had to reboot the router because it was misbehaving. I think my personal record is 90 days, and that was only interrupted because of a lightning storm, and my router is not on a UPS.
