@flashmozzg said in Qt Maintenance Tool Failed to download metadata.:
Russia. One thing to note: I think it's not only/just the number of GETs but that they all happen simultaneously that overloads my network somehow. My webpages can even briefly stop loading when Qt MT "does its thing"...
Btw, in any case spawning thousand of GETs per second is no good and I'm pretty sure it's reaching several OS limits (like max tcp connections).
Hmm... I'm quite sure that QNetworkAccessManager only allows 6 simultaneous GETS; if more are requested, they get put in a queue until one of the 6 finish.
I can't explain why your webpages stop loading though. I experience slow metadata downloads (it takes a few minutes for me), but I normally just let MaintenanceTool do its thing in the background while I browse other sites.
Anyway, I've written to the Qt devs about this, and also about other issues relating to the online installer. Anyone who's interested can join in at:
