STEPS TO REPRODUCE 1. Copy a large (in my case a 10G file) to a fstab mounted CIFS share 2. Check integrity of copied file. A CRC comparision or archive with a check will show a failed copy. 3. Note that this does not happen with Krusader, PCManFM, or even a 'cp' between the two paths. OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Tested with NFS and no corruption. Dolphin through a KIO slave is ok too. I've noticed that the copy through a CIFS mount via fstab is buffering almost the whole copy into RAM then pushing it through. Perhaps some kind of background memory issue with that route. Checked RAM sticks and tested. Swapped RAM too. It's only that copy path. I can use KIO for a bit until things settle with other parts and discuss over at the discuss area :-)
