Hi Mike,
I have experienced such a problem but on a nodebus network. The culprit was 
intermittent problem in DNBT due to effect of corrosive gases in the control 
room environment. Replacement of DNBT solved the problem. The control room was 
later installed with Purafil filters to clean the control room environment.
 
Rgds,
