TIMED_WAITING threads on Tomcat

Hi Navin,

As I could see in your report, 248 threads are in the TIMED_WAITING state. These all threads are having the following same stacktrace.

stackTrace:
java.lang.Thread.State: TIMED_WAITING (parking)
at sun.misc.Unsafe.park(Native Method)

These are your tomcat server's nio connector thread pool. Probably you have reached the limit of 8080 connectors thread pool size and all incoming requests are stacked in a queue and waiting a released thread. The default value for maxThreads is 200, but this value can be changed in your configuration. Maybe you want to reduce the minimum thread pool size of the tomcat server's nio. Typically tomcat server's thread pool sizes are defined in the 'connector' element of the "TOMCAT_FOLDER/conf/server.xml" file.
