Hello, Since the 2.1 upgrade, my tomcat5 has crashed twice with the same message: Mar 18, 2014 6:07:37 AM redstone.xmlrpc.XmlRpcDispatcher writeError WARNING: java.lang.OutOfMemoryError: GC overhead limit exceeded Mar 18, 2014 6:08:08 AM org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor processChildren SEVERE: Exception invoking periodic operation: java.lang.OutOfMemoryError: GC overhead limit exceeded Mar 18, 2014 6:08:17 AM org.apache.catalina.connector.CoyoteAdapter service SEVERE: An exception or error occurred in the container during the request processing java.lang.OutOfMemoryError: Java heap space Mar 18, 2014 6:08:26 AM org.apache.catalina.connector.CoyoteAdapter service SEVERE: An exception or error occurred in the container during the request processing java.lang.OutOfMemoryError: GC overhead limit exceeded Mar 18, 2014 6:08:36 AM org.apache.catalina.connector.CoyoteAdapter service SEVERE: An exception or error occurred in the container during the request processing java.lang.OutOfMemoryError: GC overhead limit exceeded Mar 18, 2014 6:10:48 AM com.mchange.v2.async.ThreadPoolAsynchronousRunner$DeadlockDetector run WARNING: com.mchange.v2.async.ThreadPoolAsynchronousRunner$DeadlockDetector@1c0e7773-- APPARENT DEADLOCK!!!
