Hi,

During the last few days my linux kernel has started to behave somewhat 
strangely.

A few blocks identifying HW/SW follows:

The problem manifests itself such that some processes are killed by a SIGSEGV 
and the kernel dumps a syslog error message (four examples quoted below, I'm 
sorry for the possible exaggeration in verbosity), which I am unfortunately 
not able to interpret the details of. As far as I understand it, though, the 
problem has to do with the virtual memory.

I have not seen anything like this before; the machine has run smoothly for 
the last half a year or so, never issuing this kind of errors. The last 
change made to the setup (before the problems started) was upgrading KDE to 
version 3.1, which I assume shouldn't imply these errors. Besides that the 
machine runs only SuSE officially distributed software.

Does someone have any idea what could have happened? Or could you propose some 
actions which would clarify things a bit more, concerning these problems? Do 
the quotations below give anything useful?

Thank you very much in advance,
Ch
