[steeviedude]

Have an issue with IP handsets 1140E and 1120E randomely rebooting on a CPDC R7.5 server.
Have recovered a SSH trace from one of the handsets that has expirienced the issue and was looking for some advice on debugging this output.
Handsets are C8A FW and system is patched.

First I would upgrade firmware to at least UniSTIM 5.1 (C8D) - C8A is UniSTIM 5.0 and came out with the on the 7.5 software distribution; I know for a fact it had major issues on the provisioning side. I believe UniSTIM 5.2 is out a few weeks, but I haven't taken the leap on it yet.

Next, do you have any kind of third-party QoS monitoring (NetIQ, etc.) that might be enabled? Also, I'd stick a sniffer on your network; could be a broadcast storm or something else slamming your phones' Ethernet interface.
