I have a WinNT system with SP6 and OP 4.
This system is an oracle server but is usually not connected to by any user.(IIS does connect to it)
This system also has a dialogic card installed on it.
IIS is installed and used quite often.
We also have communication over the network through TCP/IP. I have around 10 applications running on the system about 4 of which are multi threaded.
The number of threads for these applications is nominal.(2-10 per process)
Oracle usage doesnot increase very much. sometimes reaching to 40%(very occasionally).normally it stays below 10%.
The system continuosly remains above 80% causing the total CPU usage to stay at 100% and not drop at all.
Even if I kill all my applications it takes about 2 mins to reduce the CPU usage after which it reduces to about 5-10%.
I run the same applications at other systems also but donot face this problem. The CPU usge on other systems (with the same configuration ) toggles between 4-30% reaching the higher limit only when Oracle usage increases in a burst. After that it is restored to about 5% in about 1-2 seconds.
Please help me out soon as I am in crisis.
