Subject Re: [jira] Created: (NET-152) FTPClient.retrieveFileStream hangs occassionally
Date Mon, 05 Mar 2007 09:41:44 GMT
We had a similar issue which, as you have mentioned below, would occur 
"randomly" - sometimes due to firewall settings, sometimes due to active 
connection mode, and sometimes reasons that we couldnt trace.
        The workaround we applied was to set the timeout in commons-net 
for specific number of retries. After the specified retries/timeout 
expires, we would make attempts  from within our application to reconnect 
(disconnect and connect) to the same server and re-initiate the failed 
operation.

Thanks,
Deepa

[jira] Created: (NET-152) FTPClient.retrieveFileStream hangs occassionally






FTPClient.retrieveFileStream hangs occassionally
------------------------------------------------

                 Key: NET-152
                 URL: https://issues.apache.org/jira/browse/NET-152
             Project: Commons Net
          Issue Type: Bug
    Affects Versions: 1.4
         Environment: Redhat Enterprise Linux 4
            Reporter: Shashi Anand B


Occassionally, retrieveFileStream on FTPClient hangs. The thread dump 
gives the following trace:

 java.net.PlainSocketImpl.socketAccept (native method)
 java.net.PlainSocketImpl.accept (PlainSocketImpl.java:353)
 java.net.ServerSocket.implAccept (ServerSocket.java:448)
 java.net.ServerSocket.accept (ServerSocket.java:419)
 
org.apache.commons.net.ftp.FTPClient._openDataConnection_(FTPClient.java:502)
 
org.apache.commons.net.ftp.FTPClient.retrieveFileStream(FTPClient.java:1,342) 


This seems to occur randomly. Hence, I have not been able to get any 
specific information for further debugging.  Is this a known issue? Is 
there any work-around for this issue?
