Threads are in State RUNNABLE FTPCLient

                 Key: NET-443
             Project: Commons Net
          Issue Type: Bug
          Components: FTP
         Environment: WIN2003
            Reporter: Korcan

Hi there, 
I have developed new application which uses apachi FTPClient to connect to a Windows
OS FTP Server and checks approximately 4000 folders on FTP Server. 
I am generating Threads to minimize the looping over folders.Every thread tries to loop for
example 250 folders.When i run the application on my local computer WinXP no problem.When
i yesterday installed WIN2003 Server and run the application i realized that program runs
, tries 3-5 times for every thread and sleeps ...and suddenly i see that threads are blocked.

I use JRE6 and JConsole also i can see very well that every thread are in state RUNNABLE and
RMI TCP threads are time waited state.I could not find any solution the whole day. 
is it api problem or JRE problem or OS problem? 
Thanks in advance for your helps 

BTW there is a code ftp.listfiles(); threads are waiting for this i think but why i dont know
