Description Ralf Jung 2010-06-08 12:23:43 UTC 
Version:           unspecified (using KDE 4.4.2) 
OS:                Linux

When I upload a big file using the SFTP KIO slave, I get this error (or is it a warning?) repeatedly in the server logs:

Jun  7 21:02:08 xxxxx sshd[25853]: channel 0: rcvd big packet 32797, maxpack 32768

The numbers 32797 and 32768 are always exactly the same.

Reproducible: Always

Steps to Reproduce:
Upload some big (>500kb) file using SFTP

Actual Results:  
Errors/warnings in the server log

Expected Results:  
No such log entries

I did not change anything on the server and did not get this error at all up to KDE 4.3 (including).
I did not do any research to check on exactly which size it starts, but it does not happen for small (~10-20kb) text-files, and happens always for bigger (>500kb) binary files.

This is just a warning in the logd. We should fix this but it doesn't break or corrupt something.
