> 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
