<div><font face="Arial" size="2">I am currently running Opencms 5.0.1 on RH Linux Advanced Server v3, on

</font></div><div><font face="Arial" size="2">editors. Every one to two days or so for the past month or so, I have had to
</font></div><div><font face="Arial" size="2">restart Tomcat 4.1.30 as I would get OutOfMemory errors with it causing
</font></div><div><font face="Arial" size="2">OpenCMS to stop functioning. I am aware that one can add parameters to
</font></div><div><font face="Arial" size="2">CATALINA_OPTS to allow Java to use a certain size of memory viz -Xmx and
</font></div><div><font face="Arial" size="2">-Xms. I have now written a "restart" script for Tomcat which runs overnight
