? B/s: error

[NoTime1]

Hi,
when I uploading video files sometimes I get this error when speed is showing like: ? B/s. After this file is uploading not correct or stop uploading at all.

Example: I tried to upload 3 files on server, then I get this error and now on server I have 12 pieces of this files.
It happened not only on this server, so it's probably not server problem, but I'm uploading only videos and I don't know if with other file types this error exist.
Log for my example: ​https://www.dropbox.com/s/7zpgb4dhfln4ubz/filezilla.log?dl=0

Also very important thing, after this error, when files uploaded, my computer is start work crazy, every program is crashing and I can't open anything, but after restart everything is ok like nothing happened.

In past I uploaded files by drag and drop, I thought it's because of this but now I uploading from local directory tree by right click -> upload and problem still exist.

hope you can help me

In some situations speed information simply isn't available, for example when the data connection is still being established. In these cases, displaying the speed as unknown is intentional.

Also very important thing, after this error, when files uploaded, my computer is start work crazy, every program is crashing and I can't open anything, but after restart everything is ok like nothing happened.

That's a different problem. There is something wrong with your computer. It could be a corrupt Windows installation, a bad driver or defective hardware.

I recommend trying a fresh Windows installation.
