Hi Margaret Doll!

Googling "RPC:  error 5 connecting to server" yeilds much about Kernel
updates.  It may be worth updateing your Kernels, or, perhaps it is
time to go to FC5 throughout - fresh install.

I would check memory on the machines.

I would check swap integrity and use.

I would monitor the network for hardware error or being swamped.

Virus?  Bot?

Ok, I am reduced to shooting in the dark.

I do wish you Good Hunting!
