It can be caused by many things, and the probable one is the
configuration.

And BTW, your stup won't work well.
If the connection_pool_size is 60 you will have
60 * MaxClients/ThreadsPerChild connections to Tomcat, and
given your 100 limit this will not work.

The proper number is:
connection_pool_size = maxThreads in Tomcat / (MaxClients / ThreadsPerChild)

If you have in httpd.conf
MaxClients 600
ThreadsPerChild 60

and
maxThreads="100" for AJP Connector in server.xml

this would give
worker.xxx.connection_pool_size=10 (100/(600/60))
