Re: All worker threads of my tomcat have been occupied!
gotcha! I moved tomcat home directory to another partition by using 'cp -r' at that time. That's why tomcat start to reload.

Re: All worker threads of my tomcat have been occupied!
@ Chuck that's very strange. I failed to find any thread stack relevant to tomcat reloading. @ Chris No, I do not use the manager app. All settings in my server.xml are just using the default value, except one modification to block to set the real deployment path. My question is: what's the condition to trigger tomcat redeployment, and how to avoid it? after all, I don't think it's a proper setting for online server. Does it leave me no choice but upgrading my tomcat?

All worker threads of my tomcat have been occupied!
hi, all I found my tomcat refusing to work this morning. I tried jstack to get some info, and then I found a lot of thread call stack like: "http-8082-154" daemon prio=10 tid=0x7f711c21f800 nid=0x5b0a waiting on > condition [0x7f70dc887000] >java.lang.Thread.State: TIMED_WAITING (sleeping) > at java.lang.Thread.sleep(Native Method) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:132) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) > at > org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) > at > org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:861) > at > org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:606) > at > org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) > at java.lang.Thread.run(Thread.java:662) > Actually, when I used grep to get more clue # grep -B5 -A7 org.apache.catalina.valves.ErrorReportValve.invoke 14446.dump I got: Dump File: 14446.dump.1388636053 > execute external commands: ^[[01;31mgrep -B5 -A7 > org.apache.catalina.valves.ErrorReportValve.invoke^[[00m > "http-8082-200" daemon prio=10 tid=0x7f711c14b000 nid=0x6a52 waiting > on condition [0x7f70d9a59000] >java.lang.Thread.State: TIMED_WAITING (sleeping) > at java.lang.Thread.sleep(Native Method) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:132) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) > at > org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) > at > org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:861) > at > org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:606) > at > org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) > at java.lang.Thread.run(Thread.java:662) > > "http-8082-199" daemon prio=10 tid=0x7f711c148800 nid=0x69f3 waiting > on condition [0x7f70d9b5a000] >java.lang.Thread.State: TIMED_WAITING (sleeping) > at java.lang.Thread.sleep(Native Method) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:132) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) > at > org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) > at > org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:861) > at > org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:606) > at > org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) > at java.lang.Thread.run(Thread.java:662) > > "http-8082-198" daemon prio=10 tid=0x7f711c146000 nid=0x6992 waiting > on condition [0x7f70d9c5b000] >java.lang.Thread.State: TIMED_WAITING (sleeping) > at java.lang.Thread.sleep(Native Method) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:132) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) > at > org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) > at > org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:861) > at > org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:606) > at > org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) > at java.lang.Thread.run(Thread.java:662) > ... ... > > "http-8082-2" daemon prio=10 tid=0x7f711c002800 nid=0x38a4 waiting on > condition [0x7f7124b7a000] >java.lang.Thread.State: TIMED_WAITING (sleeping) > at java.lang.Thread.sleep(Native Method) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:132) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) > at > org.apache.catalina.con
