Subject: AjpNio Invalid message received on header
From: Yasser <yarafatin@gmail.com>
To: users@tomcat.apache.org
Content-Type: multipart/alternative; boundary=bcaec54d4b0207d1f704c69fb8ba

I am using Tomcat 7.0.29 fronted with Apache 2.2.22 modproxy.
Configured Ajp as the protocol in httpd.conf and AjpNioProtocol in
server.xml.
After the server starts, the logs are filled with the following message:
*Severe: Invalid message received with signature 20599
com.apache.coyote.ajp.AjpMessage processHeader*

There are no requests sent to the web or tomcat server and it still throws
that error at an interval of 20 seconds. Access logs in tomcat and apache
show that no request is coming in. What is causing the invalid message
error ?

Here is the configuration :
httpd.conf
ProxyPass /wl http:// ip : port /wl
ProxyPassReverse /wl http:// ip : port /wl

server.xml
<Connector port="port" protocol="org.apache.coyote.ajp.AjpNioProtocol"
connectionTimeout="20000" acceptorThreadCount="2" maxThreads="600"
redirectPort="8443" />
