Probe Failed

On December 17, 1999 my company upgraded from a Model 500 to a Model 720.
We also upgraded from V4R3 to V4R4. Four times since the model 720 has
experienced a very dramatic slow down. Each time this has happened, I have
found the following message in the history log

The same message appeared for the following categories. In the above
message, replace *DISK with these.
*IPCS, *LCLRSP, *IOPBASE, *CMNBASE, *CMNSTN, *CMNSAP

Has anyone had a similar problem? So far IBM Tech support has not been any
help?
