title: How to increase Maximum Memory Pool Size? Apache Tomcat 9
body: <p>I am trying to increase my Maximum memory pool in Apache tomcat <code>config</code>.</p>
  
  <p>I am using Geo-server services with the help of Apache, however my memory in Geo-server is filling very fast. All the time I have to free memory from Geo-server Server Status. </p>
  
  <p>I have to increase my memory to <code>2048 maximum</code> by stopping Apache server when I increase from <code>1024 to 2048</code> Apache is not starting.</p>
  
  <p>Can anyone guide me what to do how I should increase my memory size?</p>
