Unexpected reboots of AnywhereUSB/14 with newest firmware?

0 votes
Hello,

we had an unexpected reboot of the AnywhereUSB/14.
We never had this problem in the past aand last week we updated to the newest firmware and also the drivers for the W2k8 server. Could it be that this is a bug in the newest firmware?

Is it possible to find out why the AnywhereUSB/14 rebooted? Any logs?

Telnet or SSH to the AWUSB/14 to get into the CLI then issue the "show panic" command. What's the result?

Hi jeremym,

thx for your response! I checked via telnet and the output is the following:

But.. Which useful information do I get from this stacktrace?
It looks like you're using the Digi RealPort (serial-over-IP) driver.  This is only necessary if you're interfacing with the (DB9 RS232) serial port on the AWUSB/14, not if you're using the USB ports.  Are you actually using the serial port?  Or only using the USB ports?
Yes, we are only using USB ports. Can this cause the problem with the unexpected reboot? Can this have also other sideeffects?
Should we uninstall the RealPort driver?
I suspect that, for some reason, the RealPort driver is conflicting.  While they SHOULD work well together, maybe there's a bug somewhere.  So, if you aren't using the serial port, I suggest uninstalling the RealPort driver to see if this helps.  Uninstall RealPort by right-clicking the AWUSB in the MultiPortSerial section of Device Manager then selecting Uninstall.
Ok, thanks!
I uninstalled the driver now and will see what happens.

The last unexpected reboot was last week (5 weeks after the first error), so it happens very rarely.
I will give feedback in a couple of weeks if the problem is now solved.
Hello,
today, exactly 5 weeks after the last reboot, the hub rebootet again.

Below the stackstrace:

Isn´t it strange that this happens every 5 weeks?
Again it was not possible that the Windows 2008 R2 servers connected automatically to the hub, a reboot of the Windows server was needed. For that problem I created a other ticket: http://www.digi.com/support/forum/48970/disconnect-and-connect-anywhereusb-14-not-working
It seems to be that disabling the RealPort feature of the hub solved the problem.
We have now a uptime of 50+ days without any problems.
Excellent, thanks for the update!
