Repeating GPF
Hi I was wondering if anyone could advise on the cause of the GPF's I'm seeing in the syslog of my ReadyNas Pro. These happen once a week at least an normally result in my having to powercycle the...
We have encountered this error on a couple of client machines. It has been driving us crazy. Both machines (Pro 4 and Pro 6) have been replaced.
This is not a hardware fault as such.
In both instances the units have one Ethernet directly connected to a server on jumbo frames for VMWare. The other is plugged into the switch for management.
I believe it is something to do with a packet on the network causing the low level network drivers to crash the box.
I have found that when the problems happen I notice some other things.
1. Either just before, or soon after the GPF, there are many errors in the log as such.
Dec 29 23:28:55 PERTH-STORE01 kernel: UDP: short packet: From 192.168.60.9:17500 130/99 to 192.168.60.255:17500
The packets are always UDP to broadcast addresses. At this site there is also an NVX and there are no errors like this in the logs.
2. The management interface is non responsive, even to pings, yet the NFS interface is still alive.
3. Sometime from a couple of hours to a day or two later, it hard locks up and needs a powercyle.
We have one of these units now unplugged from the management LAN and only accessable via the connected server. So far so good. I will report back in a week or so. It usually fails within 3 or 4 days.
