    @Community: Keep up the good work

    Hi,

    Since my first encounter with RT-N66U and Merlin's firmwares (xx.21 - xx.24), once per week (every 4-5 days) I am facing router's unresponsiveness when I am trying to access it either through web interface and/or telnet/ssh.

    Needless to say that despite this, the router is still functioning (LAN, WAN access, etc) without a problem. The cure is always a reset.

    Do you guys have faced, constantly, such a kind of issue. Any help will be much appreciated.

    Regards

    Are you running Download Master or any other bittorrent client on it?

    Check on the Sysinfo page for the available RAM as well as CPU load when the problem occur, they might give a hint as to what is going wrong. Could be a service leaking memory, for example.

    Thanks for the reply.
    I do not run either Download Master (i have not installed it) or any other bittorent on router. I do run bittorents on other "devices" (PC, NAS).
    I will will monitor RAM and i will come back when the problem reoccurs (my only concern is that when it happens I can't do anything).

    BTW I suppose that these figures are OK. Aren't they ?

    Memory usage with Transmission and NFS file server

    Hi,

    Just to compare - My memory usage looks like this:
    Code:
    [B]Memory[/B]
    Total 		234.25 MB
    Free 		51.65 MB
    Buffers 	54.95 MB
    Swap usage 	2.07 / 62.75 MB
    Much less free memory and some usage of swap file due to
    - heavy file sharing with Tranmission
    - NFS file server for the Linux clients

    So your memory usage looks good! :)

    With kind regards
    Joe :cool:

    All normal. Keep an eye on this over the next few days to see if it has a tendency to go down.

    γειά σου,

    For this kind of issues it's a good idea to activate the swap.
    Even if your router runs out of physical memory it will not become unresponsive.

    Anyway, try to ping it when this happens.

    My memory usage:
    Code:
                 total          used           free       shared      buffers
    Mem:        239868       201172        38696            0        11096
    -/+ buffers:             190076        49792
    Swap:       506008         2216        503792
