ReadyNAS Ultra 2 - Suddenly inaccessible over network
Hi all,
I have a ReadyNAS Ultra 2 with firmware RAIDiator 4.2.22 on it.
I have set this little box up for testing purposes and it seems to have been working fine. It is connected to a switch with other devices on the local network. I created some mapped network drives pointing at my ReadyNAS device on a friend's PC.
This morning I had a phone call from the friend saying that their Windows Explorer was extremely slow and sluggish. On investigation, it seems that for some reason the ReadyNAS has become unreachable on the network; when I try and ping it there is no response.
The device itself was powered on and the power light was illuminated, so the device has not switched itself off. There are no network problems between the device, and everything else on the network is functioning correctly.
Looking at my system.log I see the following:
Feb 8 06:25:06 RNAS1 syslogd 1.4.1#18: restart.

Feb 12 10:47:23 RNAS1 shutdown[1856]: shutting down for system halt [[[done by me, manually]]]
It seems on Feb 11 @ 12:38:31 the device encountered some kind of problem ("general protection fault") and then again three seconds later @ 12:38:34
Slightly further down the log I see the entry "Fixing recursive fault but reboot is needed!" which is when I guess the device was lost from the network (although I have no other logging that proves this).
Then I start seeing "eth0: hw csum failure" errors at Feb 11 20:35:15, then again at Feb 12 10:12:38, Feb 12 10:14:29, Feb 12 10:15:40.
On Feb 12 10:47:23 I restarted the device and now it is functioning as expected. Also my friend's Windows Explorer is no longer behaving sluggishly.
Does anyone have any idea what could be causing this issue or can suggest any troubleshooting steps I may take?
Thank you for reading.
I have a ReadyNAS Ultra 2 with firmware RAIDiator 4.2.22 on it.
I have set this little box up for testing purposes and it seems to have been working fine. It is connected to a switch with other devices on the local network. I created some mapped network drives pointing at my ReadyNAS device on a friend's PC.
This morning I had a phone call from the friend saying that their Windows Explorer was extremely slow and sluggish. On investigation, it seems that for some reason the ReadyNAS has become unreachable on the network; when I try and ping it there is no response.
The device itself was powered on and the power light was illuminated, so the device has not switched itself off. There are no network problems between the device, and everything else on the network is functioning correctly.
Looking at my system.log I see the following:
Feb 8 06:25:06 RNAS1 syslogd 1.4.1#18: restart.
Feb 9 06:25:06 RNAS1 syslogd 1.4.1#18: restart.

Feb 12 10:47:23 RNAS1 shutdown[1856]: shutting down for system halt [[[done by me, manually]]]
It seems on Feb 11 @ 12:38:31 the device encountered some kind of problem ("general protection fault") and then again three seconds later @ 12:38:34
Slightly further down the log I see the entry "Fixing recursive fault but reboot is needed!" which is when I guess the device was lost from the network (although I have no other logging that proves this).
Then I start seeing "eth0: hw csum failure" errors at Feb 11 20:35:15, then again at Feb 12 10:12:38, Feb 12 10:14:29, Feb 12 10:15:40.
On Feb 12 10:47:23 I restarted the device and now it is functioning as expected. Also my friend's Windows Explorer is no longer behaving sluggishly.
Does anyone have any idea what could be causing this issue or can suggest any troubleshooting steps I may take?
Thank you for reading.

- I would start by clearing the active sessions via the (net use /delete *) command and then try remapping the drives/shares. I would also try disconnecting the lan cable from the readynas while running a continuous ping to it to see whether this is being caused by an ip address conflict due to a dhcp server, sounds silly but Ive seen this be the cause of the issue more times than you can imagine
- That Call Trace error can be a memory leak issue. I'd start a ticket with Netgear and send them the logs.
