Subject [jira] [Commented] (NET-443) Threads are in State RUNNABLE FTPCLient
Date Wed, 29 Feb 2012 01:36:08 GMT


Sebb commented on NET-443:

Which version of Commons NET are you using?

Note that NET does not use RMI, so the problem may be elsewhere in the application.

If you can reproduce the problem with a simple test case, please attach it to this issue.

> 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
