Description kjpark 2006-02-27 04:36:53 UTC 
I've a little cluster with 2 Tomcats 5.5.12 and 1 apache2.2 running on fedora 
4.0 linux box.
(tomcat and apache are connected by mod_jk.so module) 

During tests I have found that exception while I startup on this cluster.

Is that a known bug? Has anyone fixed this problem in an offical patch?

It is not an error to worry about. It is an incorrectly reported warning.
The sender TomcatA will periodically close its connections, and TomcatB reports
this as an error. Nothing to worry about, and in Tomcat 5.5.16 this has been
fixed  to only report a 1 line warning.
