-|During troubleshooting of some communications problems (specifically
-|token-ring errors) we discovered that CFINT01 had taken over the entire
-|system on a NON-Server box, 95% of CPU and over 95% of system memory.
-|Discussing this with support they indicated there there are other tasks
-|assigned to CFINTnn jobs besides 'CPU Burn' and some parts of
-|communications recovery is one of these tasks.
-|
-|Therefore I wouldn't dismiss CFINTnn on non-server systems, it just
-|isn't 'playing govorner' on those systems.
