Description Vance Garry 2003-03-24 18:03:02 UTC 
Version:            (using KDE KDE 3.1.1)
Installed from:    Gentoo Packages
Compiler:          gcc 3.2.2 
OS:          Linux

Uploading large files using webdav(s) through Konqueror causes unexpected results.  For instance, if I try to upload a 100M file, Konqueror will issue a "PUT /dir/100Mfile" as expected.  The upload status bar will then indicate that the upload has started and that xMB/s are being transfered (the listed transfer rate degrades over time).  However, there is no data being transfered (confirmed w/tcpdump).  After the progress indicator reaches 98%, Konqueror starts transferring data but says that the program has "Stalled."  After several minutes an error is given and the transfer stops.  Uploading a 10M file will replicate the behavior of uploading a 100M file except the upload will succeed.  Attempting to upload a 1G file will crash Konqueror altogether.  Before Konqueror crashes, it consumes all real memory (1G), starts paging, and then crashes.

I can confirm this bug and urge an fix for that. For example if you upload ~650 MB file it puts _all_ into memory and then starts transfer (the % bar is then stalled and doesn't show any progress so you don't know what is going on).

I haven't tried >650 MB files. I only tried the sum of 1.7 GB, but I aborted it before it consumed all my memory and swap.
