Tomcat problem - could not reserve enough space

I start the server with 256 MB of RAM. The maximum heap size that I can allocate for Java is 110 MB. When I add this parameter to JAVA_OPTS, I can run java -version. The problem is that I cannot start Tomcat with these parameters. The maximum heap size for Tomcat to run is 40 MB. I don’t know why I can’t allocate more memory?

Of course, I get the error:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

Set CATALINA_OPTSin -Xmx110m, JAVA_OPTS. I suppose you could set both to be sure.

The error message suggests that you do not have enough free RAM to close other applications and see if you can allocate a large heap. You may need more RAM.
