My system environment is: Windows 2000 Server. JDK 1.5, tomcat 5.5, Oracle 9 The problems are: 1. After tomcat was started, the memory of the tomcat was normal, about 200M-300M. But after a certain time(this time was not set), the memory began to grow, and the growing speed was so fast that in about 5 minites the maximum would be reached. The difference of this problem with other problems I've checked is, in other problems, the memory growing speed is continual and not so fast, while in our problem the memory didn't grow at the beginning, but after a certain time instead.
2. There is another strange phenomenon here. We restarted tomcat at 23:30 last night. We checked the log at 8:00 this morning and found out the system was not used by anyone during this time. But the memory of tomcat had reached to 1.5G, which is the maximun of tomcat's memory. Later, after some users began to use this system, tomcat' memory dropped to 500M+. How and why was the memory collected? By the way, we have cheched the code for any optimization, including StringBuffer, Vector, datasource connections, etc., which only resulted with a faster response speed for users, not any influence for the memory problem. -- View this message in context: http://www.nabble.com/tomcat-memory-leak-problem-tp21855110p21855110.html Sent from the Tomcat - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
