We are working with the following configuration: Windows 2000 Server - 8CPU jdk 1.3.1_06
Tomcat 4.1.18 - 2 separate instances (separate jvms) - Tomcat1 is used as a container for our own socket server application - Tomcat2 is used for Web application (jsp/jdbc) Note that both instances have exactly the same application. TC1 is used by hand held devices while TC2 is used by web users. The Windows server has the following applications: Oracle - 1.5GB Tomcat1 - 768MB Tomcat2 - 384MB JavaApp - 384MB Total RAM - 4GB Problematic behavior: After starting both Tomcat instances, Tomcat1 works for some time and then hangs. Tomcat1 is restarted and then works fine without any problems. Tomcat2 does not have any such problems. The hanging happens only once, that is, after both instances are started. No error or exception in Tomcat logs and application logs. Thread dump at the time of hanging shows all threads in wait state. Other servers: The above problem is observed only on servers where the multiple Tomcat instance is implemented. Other servers that are working with a single Tomcat instance do not have this problem. Log Analysis: Log shows that the socket server application receives calls, processes the same but gets stuck at the time of sending reply to the client. Client in this case is the hand held device. Reproducibility: We have tried using Apache JMeter to try and reproduce the problem but have not succeeded till now. -- View this message in context: http://www.nabble.com/Tomcat-hanging---two-instance-configuration-tf3944102.html#a11188048 Sent from the Tomcat - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
