Hello Guys, I'm using an Ubuntu 11.10 - 64 bits and a tomcat 7.0.27 with jdk 1.7.0_05 the Oracle and is showing me the following messages on memory leak or lack of space due to not rotate the objects that are in memory of tomcat (as I read the documentation for the oracle this option was to do this "-XX: + UseCodeCacheFlushing" but is not) and so he stops working, so I need to restart the service! But as a production system that is complicated, and takes place 20-30 minutes, the delay times more .. performed various types of settings in catalina.sh for tomcat to clear the cache and garbage, I increased the memory, but these settings are only postponing my problem ... someone has an idea what I can do about the application and the server? Follow the logs of what happens: mmap failed for CEN and END part of zip file .. Java HotSpot(TM) 64-Bit Server VM warning: CodeCache is full. Compiler has been disabled.
