Have you tried changing the encryption algorithm ?
Are you using compression?

El 03/11/2015 a las 08:34 a. m., Steinmetz, Paul escribi?:
I changed the SFTP process to send a 3mb zip file instead of the 110mb uncompressed file.
SFTP now working with a zipped 3mb file.
Large file issue for SFTP still exists, possibly 30 to 40mb limit.
Still looking to resolve this issue.

Subject: SFTP client via PASE, large files possibly timing out

In production, I converted an FTP to SFTP via PASE, all appeared to be working.
I did see some issue, large files are possibly timing out.
I could see this from the output of the SFTP process.
The default timeout from what I could find is 30 seconds.
I changed the timeout in the SFTP input script to 300, that appeared to make the problem worse set timeout 300 Back to set timeout 30 Are there other timeout settings or other settings that would improve large file transfers?
