Hi, We are running Tomcat 5.5.9 on Windows 2000 Server. Our test involves 500 plus clients sending periodic jsp requests.
Performance logs show that the tomcat process spikes up to 50% every 10 seconds even AFTER the test has ended and the clients have stopped sending requests. Tomcat logs showed the following two statements: Every 10 seconds: 16:59:46,599 DEBUG (HostConfig.java:960) [org.apache.catalina.startup.HostConfig::checkResources] - Checking context[/TUP] redeploy resource D:\Program Files\Tomcat\webapps\TUP Every 60 seconds: 2007-01-09 16:59:36,532 DEBUG (ManagerBase.java:653) [org.apache.catalina.session.ManagerBase::processExpires] - Start expire sessions StandardManager at 1168383576532 sessioncount 0 2007-01-09 16:59:36,563 DEBUG (ManagerBase.java:662) [org.apache.catalina.session.ManagerBase::processExpires] - End expire sessions StandardManager processingTime 31 expired sessions: 02007-01-09 I tried turning off autoDeploy. The redeploy log messages went away, but the cpu remains the same. I turned on verbose:gc and the GC logs show collection every 90 seconds or so. So that does not match the cpu spike. What does Tomcat do that could cause a cpu spike of almost exactly 50% almost exactly every 10 seconds? I have spent a couple of days searching the web, tomcat lists and bug lists without any luck. Appreciate any help anyone can provide. Thanks.
