Hi Does anybody know the reason why on 2 CPU my Tomcat is after few hours running like crazy, utilizing 50% of CPU's power. My servlets don't show anything waiting for something. When I restart Tomcat everything is ok. I added ROOT Context and it didn't help. I tried to upgrade versions, but I finished on the 4.0.1 and my ideas came to the end. With the same configuration on machine with single CPU Tomcat works fine. Thanks Tom
