Hi experts,

I have a Sun 5.9 machine, and Apache and tomcat are running to serve both html pages and Esri ArcIMS server.

I cannot load the ArcIMS pages anymore, and below is the message in the Apache error log.
I would appreciate if anyone can help to track this problem.

thanks,

What have you changed on this machine?  The error indicates a disconnect of the apache/tomcat protocol connector, the configuration files for which are in the $TOMCAT_HOME/conf and $APACHE_HOME/conf (if memory serves).  Did you upgrade Tomcat or Apache?

Can you grep (or search) through your httpd.conf for "mod_jk" or "mod_jk2" and post results;
Also, look through your $TOMCAT_HOME/conf and post contents of jk.properties (or jk2.properties);
Look through $APACHE_HOME/conf and post contents of workers*.properties.

That's a start.

To find the version of tomcat - go through the $TOMCAT_HOME/logs/catalina.out log.  When it starts up, the version is logged there.

It's odd that -  without any changes - this stopped working.  Are your machines running on Windows or Unix?  Also - does your ESRI server have a software key or a hardware key attached?  Perhaps the license needs renewal?

I stopped and restarted the tomcat service on the machine.
that seems to solve the website problem.
I might try to upgrade tomcat in the future.

thanks for your help.
