Why I got multiple/many instance of tomcat + jvm right after I've started tomcat? ( on Red Hat Linux E 3 )
Dear All,
I got 6 servers running rhel3 and tomcat 4.1.27. One of this servers
its tomcat is giving so many instance of tomcat and jvm but not for
other server. They are running with the same configuration as far as
tomcat and jvm is concern. Any thing else did I miss?
This is snippet of my server.xml for all server for Connector
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
port="80" minProcessors="5" maxProcessors="100"
enableLookups="false" redirectPort="8443"
acceptCount="10" debug="0" connectionTimeout="20000"
useURIValidationHack="false" disableUploadTimeout="true" />
A snippet of ps -aux | grep tomcat on the problematic server
[root@iedb salmonprops]# ps aux | grep tomcat

implementation in newer kernels.
