Re: [JSch-users] Problem with jsch staying in sleep state

[Butcher, W. n. U. <wil...@gb...>]

Hi 

Thanks for the reply, the problem happens on the upload, I have not checked the download as we only need to move files in one direction. That is from a Solaris server to a Windows server. The windows server is running FreeSSHD. When the process hangs I run truss on the process and find that it is just looping in a sleeping state. If there are any tests that you would like me to run then please let me know.


Thanks


William

   |Hi I have written a java sftp interface using jsch. I get an
   |intermittent problem when I try transferring a number of files up
   |to 300MB in size (up to 10 files). The transfer works and then for
   |some reason goes into a sleep state and never wakes up again so
   |the connection is maintained but the files do not transfer and the
   |process never finishes. I have done a truss on the process and
   |remains in the sleep state indefinitely. I have change my code to
   |drop the session for each file and then create a new session and
   |channel for each file, but this doesn't seem to work. Sometimes
   |the process will finish without problem but about 50% of the time
   |it seems to get stuck in a sleeping loop. Version of jsch is
   |0.1.47. Running on Solaris 10. I've tried setting
   |setServerAliveInterval(500) but that doesn't work either.

Does that problem happen on the downloading and uploading?

Sincerely,
