memory usage
Hi,
I'm getting out of memory errors on tomcat:
Mar 27, 2007 5:21:46 AM
org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor
processChildren
SEVERE: Exception invoking periodic operation:
java.lang.OutOfMemoryError: Java heap space
Mar 27, 2007 5:21:52 AM unknown unknown
SEVERE: Error finishing response
java.lang.OutOfMemoryError: Java heap space
Mar 27, 2007 5:21:51 AM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet bitstream threw exception
java.lang.OutOfMemoryError: Java heap space
There's any way to identify witch application and witch class is getting
to many memory? I think that some application creates a immense array by
never delete any data.
How can I get some statistics about tomcat's memory usage?
Many thanks!
Jordi

Read the FAQ:

The same way you would with any other Java program - JConsole is a good
starting point, but you'll likely need a profiler.
