You see the following entry in the thread dumps while analyzing a system's performance:ajp-8019- 43" nid=183 state=WAITING - waiting on <0x515a41f6> (a org.apache.tomcat.util.net.JIoEndpoint$Worker) - locked <0x515a41f6> (a org.apache.tomcat.util.net.JioEndpoint$Worker)at java.lang.Object.wait(Native Method)at java.lang.Object.wait(Object.java :485)at org.apache.tomcat.util.net.JioEndpoint$Worker.await(JioEndpoint.java :471)at org.apache.tomcat.util.net.JioEndpoint$Worker.run(JioEndpoint.java :497)at java.lang.Thread.run(Thread.java:662)Locked synchronizers: count = 0 How do you interpret this thread dump?

AThe Tomcat AJP parameter maxThreads is too small to handle simultaneous requests.

BThe JVM option maxAJPThreads is too small to handle simultaneous requests.

CThe thread is waiting for an incoming connection.

DThe system is about to crash because the thread is blocked and cannot perform its job.
The thread dump entry indicates that the thread is waiting for an incoming connection. The thread is part of the AJP connector, which communicates with a web connector via the AJP protocol. The thread is in a WAITING state, which means that it is waiting for another thread to perform an action. The thread is waiting on an object of type org.apache.tomcat.util.net.JIoEndpoint$Worker, which represents a worker thread that processes incoming requests.The thread dump entry does not imply that the Tomcat AJP parameter maxThreads is too small, that the JVM option maxAJPThreads is too small, or that the system is about to crash.
