AH01030: ajp_ilink_receive() can't receive header

I'm developing a web app with Java backend in below mention configuration with Loadbalancer ( zen Loadbalancer) environment

APP1 = Centos 7, Apache 2.4.6, Tomcat 7.0.53, Mod_Ajp connector,

APP2 = Centos 7, Apache 2.4.6, Tomcat 7.0.53, Mod_Ajp connector,

I'm having the problem after a certain period of time period tomcat JVM not responding apache request got below error in apache error log "(70007)the timeout specified has expired: ah01030: ajp_ilink_receive() can't receive header"

In web browser got "An internal server error occurred. Please try again later"

I verified both the tomcat & Apache servers are running,refer the image

But not responding jvm thread, Which means Mod_ajp connector hanged I added following entry in server.xml files. again facing same issue.

" Define an AJP 1.3 Connector on port 8009 -->

**<Connector port="8009" protocol="AJP/1.3"
 acceptorThreadCount="2" maxThreads="1400" acceptCount="200" minSpareThreads="50" emptySessionPath="true" enableLookups="false"
 connectionTimeout="180000" redirectPort="8443" />"**

My AJP setup

ProxyPreserveHost On

    RewriteEngine On
    RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
    RewriteRule .* - [F]
    RewriteRule  ^/$  /index.html  [L]
    RewriteCond %{REQUEST_URI} !^/mydata
    RewriteCond %{REQUEST_URI} !^/(shibboleth-(sp|idp)|Shibboleth.sso|SAML|server-status)
    ReWriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
    RewriteRule ^(.*) ajp://localhost:8009$1 [P]

Try setting "ProxyTimeout" in the httpd.conf in your apache configuration to the same value as the usual "Timeout".
