The error happens all the time for this file. Whenever a new log file is created it will in most cases download fine. Then, some times when the log file grows, this error will happen. When that is the case it will never download again using FileZilla.
Note:
See TracTickets
for help on using tickets.
This is very peculiar, as the SFTP code in FileZilla is based on PuTTY's PSFTP.
In particular, the short buffer detection and subsequent error is the exact same between the two.
See https://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/fxp-short-reads.html for an explanation and also section 6.4. of https://filezilla-project.org/specs/draft-ietf-secsh-filexfer-02.txt
Do you experience this issue all the time or only sometimes?
