Sounds to me like the amount of network traffic has steadily been rising over the years and that now you are approaching the max capacity of your network. Another possibility could be that one of your machines is sending rogue packets and filling up bandwidth to no useful purpose. Have you tried isolating one machine at a time to see if it makes a difference?

No, i have not tried isolating one machine yet.  It is to inconsistent to determine the effect.  I was going to look into tcpdump, to see what that could do for me!.

check also for netwatch (latest version I know is 0.7)
its not for checking packet contens, but shows very simple
who connects who at which protocol and how many packets are transmitted.

It may help to find bottlenecks.

I haven't tried any of these tools yet!
But i did upgrade to PCNFS5.1d which appears to have solved all our problems.

Thanks
