Hi team,

We are using "Pragma Fortress 5.0.10.1563" version and now in production it occasionally hang during file transfer with external sftp host.

In the software program it will run the batch sftp commands file to fetch multiple files, sample content is listed below, during the incident, we found out that the sftp command hang at the BOLD one (with underline).
We can see the 123456.tmp file is there in C:\tmp but the content is incomplete. While the second file 123457.tmp file existed but with 0 byte length.

We have checked with network team and all is fine at that moment, we are using proxy to go to outside external sftp host.
For other scenario, some times none of the tmp files there created under C:\tmp and we can see in windows task manager "Process" tab, that a sftp process is running there running the batch sftp commands file, seemingly hang.

Am wondering if you can shed some light on us e.g. any advice for workaround or strategic solution on such? BTW, to avoid posting actual business info, am all using dummy file names.

Batch sftp commands file content :
ls /reports/xxxxx.txt
get "/reports/xxxxx.txt" "C:\tmp\123456.tmp"
ls /reports/xxxxx1.txt
get "/reports/xxxxx1.txt" "C:\tmp\123457.tmp"
