Bye Bye memory

    Hi all
    I'm running Tomato 1.07 on WRT54GL v1.1

    I've noticed some strange behavior, were free memory rapidly decreases from ~5.6MB to less than 1KB(usually within one day after a reboot). I don't quite understand why this is so since I've monitered the number of open connections , which rarely goes above 300 and usually sits around 150. With 1-5 clients connected to the router. I only have a single L7 rule and a single IPP2P filter rule in QoS set. Besides that I only have a few IP based QoS rules, some static dhcp entries, and a 3.5KB firewall script for controlling inbound QoS. I've tried turning off bandwidth monitoring and internal logging. Besides that my settings are pretty much default.

    What am I not getting?

    Hmm, that's very odd.. I pretty much have the exact same set-up you do, and my memory is always about 60% free... Then again, I have a GS v 2.0, which has 32mb of RAM, but my router is only ever using about 10mb or so at any given time. Which in your case should still leave 5-6MB free, which is what you said. I do notice that if I'm using a lot of P2P, the amount of RAM used jumps considerably. I also have a couple of startup scripts that control the LEDs.

    do you mind sharing the L7 & IPP2P rules with us? :grin:
    and amount of Maximum Connection allocated in the router.
    SgtPepperKSU: thanks I haven't noticed that.

    Match Rule Class

    From 192.168.1.104 Highest

    My connection limit is 2048, which I'm nowhere near using according to conntrack (usually between 100-300 also no torrent or other P2P activity going on)

    have you tried disabling those rules?
    and could you show us a "ps" telnet into your router write "ps" and copy the respond to a post here.
    did you reset nvram after flashing Tomato?

    Did you check administration -> debug -> Count cache memory as free memory?
    That could also effect what you see.
