I have a steadily deteriorating response time condition with a development HP3000. System is a N-class, with 3 CPU. Running 7.5 PP6. Started about two months ago. Today so bad test programs can not stay connected to Quick application. Jinetd shows no issues. Stopped and restarted job anyway. No help. Linkcontrol only shows an issue with Recv dropped: addr on one path. This is a known issue with some enterprise network monitoring software that sends a packet that the HP3000 can not handle. Even HP last year had no solutions for that issue. The linkcontrol stats were reset about an hour ago. No issues reported before the reset either. No memory dump files. No jobs aborting. No hardware alerts.
The system has three network connects. Two 100BT cards, and ldev 20 is network cabled. All three have issues with ping response times. Ping from laptop reports 4 for 4 most of the time. Have seen as bad as 2 failed out of 4. Have seen response times of >75ms. Ping from development system to another HP3000 will also sometimes report dropped packets. Ping from another HP3000 to development system will also sometimes report dropped packets. Glance shows no issues, except sometimes 'TERM' wait when running Glance from two different sessions. This happens even when CPU and Memory are 1% with Glance the only active pin.
What am I missing, before dragging network personal back into issue?
