Tomcat stops responding after Broken pipes

[Mike Baschky]

Hello All,
    I've run into an odd issue with ofbiz and the embedded tomcat. Here
are the particulars - we are using ofbiz ~V4 (pulled this summer). We
are fronting the ofbiz with apache. Now here is the problem - Every so
often we'll start seeing in the log files several
javax.net.SocketException: Broken pipe exceptions in row after which the
application stops responding to web requests. Now it appears that apache
is still working and responding and the ofbiz part is still working (we
see entries in the log files from automated processes). However, the
embedded tomcat doesn't seem to be accepting web requests anymore. Has
anyone else noted this issue? If so was a fix determined.
 
Thanks,
Mike

are you using the 8443 and 8080 ports, or connecting through apache.
I would check the apache to ofbiz connection first.

Hi again,
        We are piping through apache (jk-mount port 8009). But again I
don't believe it's an issue between apache and tomcat. What leads me to
believe it's a tomcat issue is that on shutting down the application we
get an error thrown by the CatalinaContainer.java complaining about the
embedded service has not started.

Please supply logs from ofbiz that match the time this is reported in
apache.

Mike,

To me it seems to be a mod_jk problem. I remember working hard on this
and could not make it work. If you are using Apache HTTPD 2.2.x, try
switching to mod_ajp_proxy as it is easier to configure and preferred
way go.

Thanks,

Raj
