• NetMaster Network Management for TCP/IP

Issue/Introduction

Customer explained that once NF8A90 occurs on their environment the 

NetMaster (SOLVE) SSI region is restarted (per automation). 

Customer needed our help investigating it.

Environment

OS : z/OS

Release : 12.2

Component : CA NetMaster Network Management for TCP/IP

Cause

Resolution

NetMaster L2 Support explained the message--based on   customer feedback:

-

NF8A90 occurred because there was not enough CPU on the LPAR where Net-

Master (SOLVE) SSI region runs--combined with the fact that TCP/IP had 

a higher dispatching priority (DP) than NetMaster (SOLVE) SSI region.

The NetMaster (SOLVE) SSI region has to have the same DP as the stack   or it   

will not be able to keep up with the flow of packets.
