I have a user who is trying to upload a PDF to an FTP site. Small PDF's upload without issue but she is having an issue uploading a PDF tha tis 71mb. I noticed that the 7.3.2 release notes suggest that an issue was fixed that appears to be the same as what I am experiencing.
Excerpt from Release Notes below:
When a large file was received from a client for uploading to an FTP server, no keep‑alive messages were sent back to the client while the file was still scanned, which caused the client to close the connection and led to a failure of the upload. (851385)
The upload works without a hitch if I add it to the whitelist however I do not want to do this as a permanent solution. Does anyone have any recommendations for a fix?
does the user get any specific error message?
What do the logs say as for a block reasons?
You might want to try rule tracining as well to see where it upload 'hangs'.
After a while, the user gets a bad response error message and the upload fails. She does not have an issue uploading smaller files to the same site.
I ran a rule trace and didn't see any thing out of the normal.
