Hi all,
 
I eventually found the problem .... it was ncftp that was not exiting
properly from a script that was run from cron. There must be some sort of
exceptional conditions that happen as 98 % of the time the script runs with
no troubles. I'll be looking into that some time soon.
 
Cheers for all those that replied.
 
Mark

Subject: SUMMARY: Funny things happening with Swap



Hi all, 

I got many replies (thanks) and there seem to be 2 prodominant solutions: 

1)      Many thought that it could be a process that was dumping a large
file to tmp and using all the available space. 
2)      Some thought that it could be an operating system fault with a swap
space larger than two gigs. 

I have been monitoring the system for the last few days using top and lsof.
The bad news is, as of yet I haven't found the problem. The system hasn't
given me any further troubles since sending that mail. "Murphy's law" !!!

Thanks 
Mark
