[webkit-dev] Hanging builds

[Nikolas Zimmermann]

Good morning WebKit folks,

I'm looking at build.webkit.org/waterfall, and see several bots which are idle, but still report "building < 1min" pretending they would do something.
Does any of our build.webkit.org masters know the cause of this? They all seem to hang in the "upload" step. Can we detect these errors, and avoid that?
Maybe sth. like a 30min timeout timer for this step?

Thanks in advance,
Niko

P.S. I'm aware that a master restart would "fix this", but maybe we can try better and avoid that completely.
