Update 1:
Change settings to: 5 Max parallel uploads, and 3 Max upload per host.
Now it works better... sometimes 7 uploads, but maybe because 2 others are almost done, or are not responding (or waiting)... as far i can see that is the reason (not all 7 slots are uploading, but Phex still shows them in the upload-field with status 'Uploading')
See screen:
Update 2:
Change settings to: 5 Max parallel uploads, and 3 Max upload per host, Max queue length: 10
Now Phex is gonna upload to alot MORE then 5 parallel uploads! So... wrong settings!
Update 3:
Change settings to: 5 Max parallel uploads, 3 Max upload per host and disable Upload Queuing.
Now is works fine, uploading to 7 (everytime 2 are waiting, see screen above)
Update 4:
Change settings to: 10 Max parallel uploads, 1 Max upload per host and disable Upload Queuing.
Works fine too...
Conclusion: probably an 'Upload Queuing' bug... when i enable this after i set more max parallel uploads (10), then it's going wrong...
And Phex seems to ignore the "Max upload per host" setting.
