Tom,
 
Your current machine may be undersized for Interactive use.  The following change in V4R5 describes how Interactive use is now handled.  If your interactive feature is small and you run heavy interactive, then you would have seen CFINT very active on you r 4.3 system.  V4R5 changed that to the message you are seeing on QSYSOPR. One thing you would see under V4R5 is the priority of the interactive tasks moving from a 20, to a 36, to a 45, up to a 89.
 
There are two new System Values options that set by default:   QDYNPTYADJ and QDYNPTYSCD set to a 1.  These control the limit on Interactive use according to the feature card installed and throttle Interactive use by changing the priority and displaying the message you are getting..  If these options are set to 0 then CFINT will kick in and Interactive could use all of the processor. 
 
New in V4R5.  Download the manual from IBM's Publib Web Site --- "AS400 Performance Capabilities Reference".  Chapter 2 explains the changes in the Interactive environment.
 
Excerpt from the manual:
 
"In V4R5 there are several new 2xx, 8xx and SBx model servers.  These new server models utilize an enhanced server algorithm that manages the interactive CPU utilization.  This enhanced server algorithm may provide significant user benefit.  On existing models, when interactive users exceed the interactive CPW capacity of a system, additional CPU usage visible in one or more CFINT tasks, reduces system capacity for all users including client/server.  New in V4R5, the system attempts to hold interactive CPU utilization below the threshold where CFINT CPU usage begins to increase."
 
Quite a nice technical explanation in the manual.

We recently upgraded our 720 from v4r3 to v4r5.  Now we're seeing lots of messages telling us that we've our interactive threshold (never happened at v4r3 or earlier).  Anyone know of a PTF to address this issue?
