Modern version will log an info message during startup, for older ones you can do strings modules/mod_jk.so | fgrep 1.2. Version 1.2.25 is the most recent (and recommended). below is my apache conf file to load mod_jk = LoadModulejk_module modules/mod_jk.so JkWorkersFile /usr/local/tomcat/conf/workers.properties JkLogFile /etc/httpd/logs/mod_jk.log JkLogLevelinfo Better use the default JkLogStampFormat, then you will profit from improvements there (e.g. since version 1.2.25 we log milliseconds by default, unless you are using an old hard-coded JkLogStampFormat). JkLogStampFormat "[%a %b %d %H:%M:%S %Y] " Alias /testPortal /usr/local/tomcat/webapps/testPortal JkMount /*.jsp ajp13 JkMount /*/servlet/ ajp13 OK, so you are not usiung ajp12 and inprocess workers (good) and you can delete the respective config items in workers.properties. Since you don't use the loadbalancer either, you can also delete those lines (or instead replace "ajp13" in the JkMount by "loadbalancer"). My tomcat version is 4.1.12 Oops, that's very outdated, and maybe here's the reason for the error messages. It could very well be, that Cping/Cpong were invented after 4.1.12, so the Tomcat connector might not know about this protocol. If you need to stick to 4.1, that version is still well maintaoined. Please update to 4.1.36 and try again. Thank you very much. Regards, Martin Regards, Rainer Rainer Jung-3 wrote: Hi, we can't identify your problem without knowing your configuration.

Re: tomcat mod_jk error log
Hi, we can't identify your problem without knowing your configuration. Please give us - your operating system - your Tomcat connector configuration for the connector you talk to via mod_jk - your workers.properties - your httpd JK-directives - your Tomcat-version and mod_jk-version You can furthermore improve the chance of finding your problem by running your test case when having "JkLogLevel debug" and posting the full jk log file in addition. I would guess, the problem could have to do with a firewall dropping idle connections between Apache and Tomcat? If so, look at the Timeouts documentation page of mod_jk.
