I can reason why the OS (win2000) shows more threads running than a thread dump in the Tomcat console but what are these threads?

When I turn on tomcat through a windows console (java.exe)...I see 31 threads running according to the Windows Task manager...I'm guessing there are 3 extra threads that tomcat needs to talk to native Windows code... When I do a control break in the windows console I only count 29 threads: 1 "Thread-1" 5 Ajp13Processors.... Ajp13Processor[8009][4] - Ajp13Processor[8009][0] 1 Ajp13Connector 5 HttpProcessors....HttpProcessor[8080][4] - HttpProcessor[8080][0] 1 HttpConnector 8 StandardManagers eg: StandardManager[/tomcat-docs],StandardManager[/examples]... 1 "WebappLoader[/examples]" 1 "Signal Dispatcher" 1 "Finalizer" 1 "Reference Handler" 1 "main" 1 "VM Thread" 1 "VM Periodic Task Thread" 1 "Suspend Checker Thread" So are they supposed to correspond? -----Original Message----- From: Marco Trevisan [mailto:m.trevisan@;ZUCCHETTITOOLS.COM] Sent: Wednesday, October 16, 2002 8:40 AM To: [EMAIL PROTECTED] Subject: Re: debug Servlet If you launch Tomcat on a windows console with CTRL-BREAK you can list all running threads.
