I am running a test and after 500 users or so, I start to see performance degradation. I have Apache as webserver and Tomcat to serve dynamic content.
I took the thread dumps and I see most threads are waiting on "Object.Wait" as follows: at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:474) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:661) - locked [0x00002aaac91012b0] (a org.apache.tomcat.util.threads.ThreadPool$ControlRunnable) at java.lang.Thread.run(Thread.java:595) It looks to me they are waiting for threads. Currently thread limit on each of 2 tomcat servers is set to 250 each. Also, I am looking at server.xml and I see multiple sections and not sure where to increase thread number. Should it be for both of the below sections? <!-- Define a non-SSL HTTP/1.1 Connector on port 8080 --> <!-- Define an AJP 1.3 Connector on port 8009 --> Thanks -- View this message in context: http://www.nabble.com/Object.Wait%28%29-in-thread-dumps...-tp25492105p25492105.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
