Hi Ingo,

I thought that oringally and ran memtest on it for 8hrs. Not a long time I know, but there were no errors. If you reckon running it for 24hrs solid might display a memory problem I will try again.

This is my only machine running linux, so I dont have any identical hardware to test against.

Thanks,
Stephen

This might be single bit (memory) error leading to failed NULL checks.

e.g. 

if (pointer == NULL) 
   goto bail_out;

will fail.

Could you run memtest on this machine?

Did you see it on any other machine with identical hardware?
Did see it on any other machine at all?
