      Description

      Enviroment : ECperf 1.0 benchmark tests, Sybase's app server (EAServer 4.1.3), 1.4.1-beta (build 18) HotSpot VM with -server option, Windows 2000 5.00.2195 service pack 2.

      ECPerf 1.0 is a complicated benchmark. Basically, on our test condition there are around 400 EJB clients plus some http servlet clients doing the request to EAServer. The total number of threads may exceeds 1000. The detail could be found in http://java.sun.com/j2ee/ecperf/

      The system was in a complete hang state. Requests are all waiting for something. The end of the log file is the thread dump info, you don't need to look at the first part of the log file.

      I just tried Client VM, and it went through without hang. This was done on windows environmet. We did not set up the benchmark environment on Solaris. It is really complicated to setup the benchmark environment. You need 3 NT boxes to
      do that.

      Here is a list of the JVM options we used(exclude -D options)
        -server
       vfprintf
       exit
       abort
       -Xnoclassgc
       -verbose:gc
       -XX:NewSize=100M
       -XX:MaxNewSize=100M

      Attached it the app server log.
