Hello guys,

I am using winscp 4.0.0 (Build 342) to do the uploading and downloading tasks from our sftp server(SFTP-3). All goes well, until 1 week of straight operation. The server suddenly stops responding. I don't think it concerns about network connection since the application(java) who calls sftp operation can run fine if it is restarted after the hang-up is discovered. Below is the snippet of the logfile:

As you can see, the above session is not closed, which causes the process(java) to hang-up.

I would appreciate if somebody direct me to the right path.

Thanks,
Rey

Sorry, I do not understand what the log file should show. Please try to explain again.
