Folder does not exist - ftp timeout

[EricDHH]

A bug that happened when the ftp has a forced timeout, the dns323 give 5-10 minutes to connections. If nssbackup do other things than using the link after test button, the backup fails after the timeout. I switched the timeout from 5 up to 10 but in full backup situations this is not enough. I watched the lan with the status panel, there is no transfer for minutes but heavy tar and gzip activity.

Found a nice logfile that shows the problem.

nssbackup goes into the backup folder and visit older backups there.

Lots of scary errors later, seems root cannot read all files. We see a 15min hole where the ftp cancels the connection.
