I've been using RNDU4000 on 6.x os for a long time and it was mostly fine. However, lately, such things started happen: all of sudden, every few weeks or so, I can no longer access the NAS. It does not respond to ping. However, it's LCD displays correct IP address. When I unplug network cable, it says network changed. When I replug cable, it again says network changed, but says No IP address, as if it would not get one.
I do not rule out my router acting up, but how do I figure out what's going on?
here are some excerpts from the log around the time where I expect this happens:

Sep 01 21:11:25 nas kernel: Fixing recursive fault but reboot is needed!
sorry for very late reply, but I was on vacation, then on business trip..
anyway, now it happened again, and RAIDar is not able to locate it either. Looking at it physically it still shows correct IP address, so it thinks it's fine, but it's not.
