hello, i also have the problem that my tomcat stops does not respond, and this more than once a day.
i'm currently looking for the cause of the problem, so i wrote a monitoring script that collects the top-output, does a thread-dump on the tomcat-process and performs a `netstat -p -n`, and finally sends this information via email. configuration is hold by a configuration file, whereas these days i put more and more configuration into the script itself, so separation of concerns is broken :) you can place the script in /etc/init.d/ and register it via chkconfig, configurations are placed in the conf-file and in the top of the monitoring-script, you should adapt all to your needs. as i don't know if attachments are handled properly by this list, i put the script on my website, so you can find it here too: http://www.javakaffee.de/jspwiki/Wiki.jsp?page=ServerSideDevelopment i hope it's helpful, cheers, martin On Thu, 2005-02-10 at 12:12 -0800, Robert McIntosh wrote: > Hi Paul, > > I hope you don't mind the direct e-mail.
