High CPU usage with emagent.exe when system is very busy
530698Aug 29 2006 — edited Sep 6 2006We have run into an issue with the emagent consuming a lot of CPU when our databases and overall systems get taxed. It does not appear that the emagent is the cause of the initial problem. But once resources start to get taxed and there is an overall slowdown in performance, the emagent starts consuming more and more CPU. Messages appear in the log indicating that it is waiting on certain actions, such as:
:activity_pending is due to run again but is still running from last schedule
It is almost as if the longer it takes to get a response the harder it tries and the more resources it consumes. In other words, it is making a bad situation worse. It would be nice if there were some configuration parameters that could limit the retry rate.
Has anyone run into this issue? I have opened an SR with Oracle support a few months ago but haven't got anywhere.
The OS is AIX 5.3 and the grid version is 10gR2.
