Re: mod_jk CLOSE_WAIT state and 1 byte recv buffer
hello, i have a similar (the same?) problem, where i currently do not know what's really the root cause of it. i was monitoring my webapp (apache 2.0.52, tomcat 5.0.28, mod_jk2, later tomcat 5.5.7 with mod_jk 1.2.8) on port 80 (apache/mod_jk) by requesting a given url with curl. sometimes the url was not reachable, the output of curl then was curl: (6) name lookup timed out. the netstat-output was sometimes ok (cons in state ESTABLISHED), but sometimes it looked like the following: tcp1 0 127.0.0.1:50195 127.0.0.1:8009 CLOSE_WAIT 12109/httpd tcp1 0 127.0.0.1:50203 127.0.0.1:8009 CLOSE_WAIT 12113/httpd tcp1 0 127.0.0.1:50228 127.0.0.1:8009 CLOSE_WAIT 12108/httpd tcp1 0 127.0.0.1:50215 127.0.0.1:8009 CLOSE_WAIT 12111/httpd tcp0 0 127.0.0.1:50258 127.0.0.1:8009 ESTABLISHED 12112/httpd tcp0 0 127.0.0.1:50262 127.0.0.1:8009 ESTABLISHED 3268/httpd tcp0 0 127.0.0.1:50240 127.0.0.1:8009 ESTABLISHED 12110/httpd tcp0 0 127.0.0.1:50244 127.0.0.1:8009 ESTABLISHED 13759/httpd tcp0 0 127.0.0.1:50249 127.0.0.1:8009 ESTABLISHED 12114/httpd tcp0 0 127.0.0.1:50254 127.0.0.1:8009 ESTABLISHED 12115/httpd tcp0 0 :::127.0.0.1:50238 :::127.0.0.1:3306 ESTABLISHED 12562/java tcp0 0 :::127.0.0.1:50237 :::127.0.0.1:3306 ESTABLISHED 12562/java tcp0 0 :::127.0.0.1:8009 :::127.0.0.1:50262 ESTABLISHED 12562/java tcp0 0 :::127.0.0.1:8009 :::127.0.0.1:50258 ESTABLISHED 12562/java tcp0 0 :::127.0.0.1:8009 :::127.0.0.1:50254 ESTABLISHED 12562/java tcp0 0 :::127.0.0.1:8009 :::127.0.0.1:50249 ESTABLISHED 12562/java tcp0 0 :::127.0.0.1:8009 :::127.0.0.1:50244 ESTABLISHED 12562/java tcp0 0 :::127.0.0.1:8009 :::127.0.0.1:50240 ESTABLISHED 12562/java then i added the hostname of the requested url to /etc/hosts, and since then everything was ok. adding the hostname to /etc/hosts was my last action, after that i was not further debugging. my environment: 2.6.10-1.760_FC3 tomcat5-5.5.7-2jpp httpd-2.0.52-3.1 mod_jk-ap20-1.2.8-1jpp cheers, martin On Fri, 2005-02-18 at 15:49 +0100, Michael Stiller wrote: Hi, i have the following problem with mod_jk from tomcat-connectors (1.2.5 - 1.2.8) including 1.2.9 (from cvs).

Re: Restart-On-Failure for Tomcat?
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.

built mod_jk2 on fedora with tomcat 5.0.16 (working)
hi all,
after very long nights, i finally got mod_jk2 built so that it
now works on a fedora system with with apache2 and tomcat5.
i don't know if everything i did when building and configuring
is really required, but with the given steps it worked for me.
as i read a lot on this list i want to give this back to you,
perhaps it's useful for someone and saves some time.
if you find things which are unnecessary or unimportant, please
post it.
