Tomcat says OutOfMemoryError every time when I visit JasperServer application deployed to wepapps

Question

I installed the jasperserver(version: 5.6) in Windows 7 through the official document, use an exsiting Tomcat(version: 7) and an existing PostgreSQL(version: 9.2.8), I checked the installation.log file in JasperServer's installation path, and everything is OK. But when I starting the Tomcat by double click 'Tomcat.exe' and it always says the following error:

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "RMI TCP Connection(idle)"

I searched for these problem and some says to configure the JVM options in %CATALINA_HOME%\bin\setenv.bat or %CATALINA_HOME\bin\%catalina.bat, but I can't find any one of them. I think this is because I'm using an exsiting Tomcat and the installation of JasperServer modified some files in %CATALINA_HOME%. So I searched 'setenv.bat' from %JasperServer% and find it in %JasperServer%\scripts. Here is my configuration:

set JAVA_OPTS=%JAVA_OPTS% -Xms2048m -Xmx3072m -XX:PermSize=1024m -XX:MaxPermSize=2048m -Xss2m -XX:+UseCompressedOoops -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled

Also, I did followed the official document here, and nothing helps, Error exists.

Is there anyone who met the same problem? What should I do? I really need help. Thanks.

It seems like the memory parameters you have specified have not been picked up? Check it out, for example by looking at the process table similar to following example:

ivos-mbp:demo ivomagi$ jps
1562 start.jar
1572 Jps
my-mbp:demo me$ ps axu 1562
USER      PID  %CPU %MEM      VSZ    RSS   TT  STAT STARTED      TIME COMMAND
me  1562   0.2  2.8  2965576 230784 s001  S    12:17PM   0:22.62 /usr/bin/java -Dcom.sun.management.jmxremote -Xmx168m

In case you do not see the specified -Xmx3072m in the printout, you need to doublecheck where from the configuration is loaded.

Thanks for your quick answer and sorry for the late reply, but I'am running JasperServer on Windows system, so I can't run `ps axu` command. Thank you again for your reply. – Alvis Aug 30 '14 at 16:25

Please, set CATALINA_OPTS instead of JAVA_OPS. Tomcat refers to CATALINA_OPTS on the start:

set "CATALINA_OPTS= -Xms2048m -Xmx3072m -XX:PermSize=1024m -XX:MaxPermSize=2048m -Xss2m -XX:+UseCompressedOoops -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled"
