I just have this problem. Using redhat 4.
I can upload anything but this one really big zip file (30mb).
I can create/delete/download/upload , everything works great but this particular file.
I've tried configuring/re-configuring the vsftpd.conf in about 50 different ways all to the same conclusion...
When the upload hits 20000000 bytes transfered it drops the connection like a hot potatoe. No errors logged or given other then "consult your administrator" ...
I guess this leads me to believe it's not something in vsftpd it's something with redhat?
Any Ideas or suggestions will be greatly appreciated.
