Upload problems with large files on WebDAV

Postby Detlef Schmuck » 27 Nov 2009, 13:35

Large file uploads with the WebDAV protocol require much free memory (RAM).

This problem occurs with the WebDAV protocol only, while the TeamDrive HTTP protocol can upload large files with limited RAM without any problems. There is no limit in the number of files which the client can watch and sync. Unfortunately the WebDAV protocol we use uses a lot of RAM during the local upload process. It needs up to 3 times free RAM of the file size to upload. If multiple TeamDrive threads try to upload large files this phenomena multiplies the problem.

TeamDrive crashes when there is not enough free memory (RAM) available to complete the task.
We are looking for a solution to improve the client WebDAV protocol to handle large files in a similar way as our TeamDrive HTTP protocol does.

If a client crashes for this reason please try the following.
1)Take a look into the Upload list in the message view. Make a note of the large files which are attempted to upload.
2)Stop TeamDrive (Quit the application)
3)Remove the large files from the watched folder (Space) in the file system.
4) Start TeamDrive and empty the trash of the desired space. (Delete files finally)

If this does not help, please contact our tech support team via email support@teamdrive.net . Paying customers will get free remote support to solve this problem.

Das Problem ist mir auch aufgefallen - ich wollte 2 Dateien á 700 MB hochladen - da hat er aber "Netzwerkfehler" gebracht.

Ob das mit dem fehlenden Ram zusammenhängt - die Maschine hat 4 GB Ram (Win 7 Prof.) - ich weiss es nicht.

Ich habe jetzt aus den 1400 MB Daten 1000 Dateien á 1,4 MB gemacht - Teamdrive rennt und rennt und rennt und rennt - ohne Probleme.

Das müsstet Ihr vielleicht noch anpassen - und vor allem die Fehlermeldungen - aussagekräftige Fehlermeldungen - Serverfehler - naja - kann viel heissen :-(

man sollte hier noch folgendes anmerken. hatte das gleiche Problem, allerdings bereits mit 230MB großen Dateien (4GB Ram System, 64bit). mein teamdrive stürzte dann allerdings immer sofort nach dem Start ab. Somit war es nicht möglich, den Papierkorb zu löschen - vom Start bis zum Absturz vergingen keine 3 Sekunden.

Lösung: Internetverbindung kappen, damit Teamdrive nicht online geht. (nur Sync ausschalten war leider auch nicht mehr möglich) Ohne Verbindung kann man die großen Dateien löschen und sync geht wieder.


my teamdrive was crashin all the time because of the big files (crashing immediately after starting). i was not able to delete files / trash or to stop sync manually.

solution: go offline (with your computer). then teamdrive is not able to connect any more. you have now the time to delete the files and empty the trash. after that reconnect your computer with the internet => working again.

Man kann TeamDrive auch Offline starten. Dazu muss in der TeamDrive.ini "online=false" gesetzt werden.

Wo die Datei liegt, ist hier beschrieben:
