ClientAbortException (broken pipe) serving error pages

[Hansen]

Hi,

I frequently receive the following exception. It indicates that the
connection is reset when sending the error page to the client. This kind of
exception is normal OK to ignore. But before I change the log level for the
corresponding package to get rid of the noise, I want to make sure that this
dose not imply other similar problems that anyone has experience and which I
should not ignore.

For further information, I am running ofbiz on port 8080/8443 and have
iptables to forward 80/443 to them.

Thanks,
Hansen

I'd recommend to use this instead of iptables

I do not think there are advantages to use apache in front of tomcat just
for port forwarding unless there are other concerns using iptables.

Thanks,

Yes, I suggested because mod_rewrite and let HTTPD deals with static content are often needed also...
