Application Servers Information - Apache Tomcat - Setting the maximum heap size for the Apache Tomcat UNIX

Mon, 01 Jan 0001 00:00:00 +0000

Safe advice :
To avoid OOME in organization deploying CAST solution, not in a 24x7 mode, I would recommend to shut down Tomcat every night, and relaunch a fresh instance. So any memory leak become harmless, unless you have 500 heavy users.
This can be automated very easily.
