Hi, We are facing some problem with tomcat which takes 95% of the CPU. - We have got a SPARC Solaris 8 with more that 4 CPUs and 8GB RAM.
- We have got one instance of tomcat 3.3.1 installed in this machine with JDK 1.3.1_05. - What we observed is that, after 20 minutes for no reason the tomcat uses almost 80-90% of the CPU. And it stays at the level itself. - The load on the server is not also high. The tomcat log does not show any problem. Restarting tomcat helps. But again after 20 minutes the same problem is happening. - There is only one context in this context. There are no multiple webapps running in this tomcat. - Another thing we observed was, turning ON the logs of our web application helps. At this point, tomcat does not use much CPU. Usually, application logs would be turned off to improve the performance. But in out case, the turning on application logs helps. Has anyone faced this kind of behaviour. Any help on this would be of great help. Note : At this point, for various reasons, we can not upgrade the version of tomcat. Any pointers on 3.3 version would also help. regards Rajesh.B
