[SLUG]kernel panic - security?

[David <david@xxxxxxxxxxxxx>]

I've had a series of these lately, and have put it down to a possible
motherboard problem - its 4 years old and been in 24/7 use all that time.

However, I wondered if maybe its something more sinister.

The message is as follows:

Lockd: connect from unpriviledged port: 203.42.45.8:4389 <4> locked:
accept failed (err 11)!

Kernel panic: skput:over: c4832b30: 13264 put 13264 dev: eth0

In swapper task - not syncing


I have no idea what or who 203.42.45.8 is, and nslookup  doesnt find it.
Nor does ping.


Any thoughts?

TIA, David.
