CentOS - May 2008 - can't get Tomcat5 to work on centos 5.1, how do I get it to work?

Hi all

A client of ours wants Tomcat 5 to be installed on a CentOS 5 server, I 
naturally just ran "yum -y install tomcat5 tomcat5-webapps 
tomcat5-admin-webapps" which installed it without any errors. Then I 
typed in service tomcat5 start, and tries to access it as such "lynx 
http://localhost:8080/" but keep on getting an error "connection
refused"


[root at vps06 /]# service tomcat5 start
Starting tomcat5: lock file found but no process running for
pid 19684, continuing
                                                           [  OK  ]

I don't see any tomcat errors in /var/log/messages but get this:

[root at vps06 /]# tail -f /var/log/tomcat5/catalina.out
   at 
org.apache.catalina.core.StandardService.start(catalina-5.5.23.jar.sonuy1u1.so)

   ...2 more

   at java.lang.Runtime.exitNoChecks(libgcj.so.7rh)
   at java.lang.Runtime.exitNoChecksAccessor(libgcj.so.7rh)


I don't know Tomcat at all.

Can someone please help me with this?

It looks like it's running out of memory when starting more threads.
Did you check if you have enough memory in this server to run Tomcat?
I think you need at least 512MB for it, but I would recommend more.

I know there are some tunings made to the JVM for it to request more
memory. If you do "ps -ef | grep java" when Tomcat is started you will
see some parameters starting with -X that will specify memory sizes,
check how much it requests. I don't really know how to tweak those,
check the script that starts Tomcat to see if it allows changing them.

HTH,
