I used command <jstack> to dump threads of tomcat, and I found that 183 threads are blocked, why?
thread dump like this: Deadlock Detection: No deadlocks found. Thread 2584: (state = BLOCKED) - java.lang.Object.wait(long) @bci=0 (Compiled frame; information may be imprecise) - java.lang.Object.wait() @bci=2, line=485 (Compiled frame) - org.apache.tomcat.util.net.JIoEndpoint$Worker.await() @bci=8, line=458 (Compiled frame) - org.apache.tomcat.util.net.JIoEndpoint$Worker.run() @bci=11, line=484 (Interpreted frame) - java.lang.Thread.run() @bci=11, line=662 (Interpreted frame) Thread 2583: (state = BLOCKED) - java.lang.Object.wait(long) @bci=0 (Compiled frame; information may be imprecise) - java.lang.Object.wait() @bci=2, line=485 (Compiled frame) - org.apache.tomcat.util.net.JIoEndpoint$Worker.await() @bci=8, line=458 (Compiled frame) - org.apache.tomcat.util.net.JIoEndpoint$Worker.run() @bci=11, line=484 (Compiled frame) - java.lang.Thread.run() @bci=11, line=662 (Interpreted frame) Thread 2572: (state = BLOCKED) - java.lang.Object.wait(long) @bci=0 (Compiled frame; information may be imprecise) - java.lang.Object.wait() @bci=2, line=485 (Compiled frame) - org.apache.tomcat.util.net.JIoEndpoint$Worker.await() @bci=8, line=458 (Compiled frame) - org.apache.tomcat.util.net.JIoEndpoint$Worker.run() @bci=11, line=484 (Interpreted frame) - java.lang.Thread.run() @bci=11, line=662 (Interpreted frame) ... thanks.
