[users@httpd] Httpd using 100% cpu

[Prasanth Kodakandla]

Hi ,
I am seeing that the httpd process is using 100% cpu .
Apache server is 2.4.6
below is the config i am using
<IfModule mpm_event_module>
    ServerLimit             32
    StartServers             6
    MinSpareThreads        300
    MaxSpareThreads        600
    ThreadsPerChild         50
    MaxRequestWorkers     1600
    MaxConnectionsPerChild   0
</IfModule>

using mod_proxy module and reverse proxy to tomcat
ProxyRequests on
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/

Need help in understanding why this is happening

Thank you
