I hope my lengthy message won't put your help away. I am trying to state my problem as clear as possible.
Problem summary: Production tomcat server was upgraded from 3.3.1 to 5.0.28 about 3 weeks ago. It hang up every 1 or 2 days during weekdays, depending on web server traffic. Windowns 2000 with SP4, JDK 1.5 and J2EE 1.5. Tomcat 5.0.28. This web application had been running smoothly with tomcat 3.3.1 + JDK 1.3.1 + J2EE 1.3 for about 4 years. Any source code (java, jsp, oracle related scripts, etc.) related to Web application was not changed during tomcat upgrade. Compiled successfully with JDK + J2EE 1.5 with option "-source 1.4". It is a single tomcat server on a physical machine dedicated to this single web application. And a single Oracle database runs on another physical machine. I read through tomcat documentation and googled archived mailing list - MARC. Doubted and tried the following things, but finally did not fix my problem: 1. No apache is used, so not a problem caused by a connection between apache and tomcat, as described by Richard on 12/9/05. 2. It is an in-house application and accessible within the company only. There is no firewall related issues. 3. It is WIN2K, so it is not a problem related to Linux environment. 4. No tomcat built-in database connection pool is used. Instead, this pool is implemented and managed in my packaged java only. In another word, this db connection pool is outside of tomcat. This problem is not related to tomcat connection pool memory leak. 5. Mentioned in Tomcat 5.0.28 release notes, java compile memory leak was fixed in JDK 1.4+. This is not the cause to my problem. 6. Patched with Leo's bugzilla 36541. Hang again 22 hours later. What's next? I have been on roller-coaster for a while. It is not fun at all. I appreciate any clues in advance! - Monica --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
