Can't increase the Max pool memory from tomcat5w.exe for a tomcatservice

This is a discussion on Can't increase the Max pool memory from tomcat5w.exe for a tomcatservice within the J2EE forums in Framework and Interface Programming category; I have a tomcat service on a windows 2003 server. I have a 4G RAM on this server machine. When I try to increase the Max pool memory from the tomcat5w.exe tool by inserting 2000 in the Max pool memory text field, and try to restart the service; it gives me an error and the service does not get restarted. Does any one have any suggestion or has experienced similar problem? Thank you in advance...
