Bob-

Yes, the exact configuration would be useful, but there's the rub.

The configuration is pretty simple: it's the (current) final release of OpenWRT "Attitude Adjustment" running on a Ubiquiti PicoStation 2HP. There's an Ethernet port and two VAPs: one a regular Access Point, one a mesh access point.

I have this configuration running in four different places (including my own home), and it fails in two. In the other two locations, it runs perfectly - "free" always reports the same number (more or less).

In the two places it is failing, it is only the "stand-alone" node that fails - the one connected to the router works fine.

On the node to which I have ssh access, I can see that it takes about 7-8 hours to fail. There is very little WiFi interference and no one connects to it (it's out on the back of a barn, strictly for stability testing).

On the other node (it's in a different network in a different location, BTW), it is in a very congested area, with many WiFi APs around, and it is being heavily used.

This is the wireless config in OpenWRT:

config wifi-device  radio0
    option type     mac80211
    option channel  10
    option phy    phy0
    option hwmode    11g

config wifi-iface
    option device   radio0
    option network  lan
    option mode     ap
    option ssid     'AccessPoint'
    option encryption mixed-psk
    option key Password

config wifi-iface
    option device    radio0
    option network    lan
    option mode    mesh
    option disabled    1
    option mesh_id    mesh_id

I'm not quite sure where to go with this from here. If I could get it to fail consistently here, I could probably come up with a way to debug it (serial port, etc.) But it only fails in places where I can't get my hands on the radios.

I am REALLY open to ideas here...

Thanks,
