OSError: [Errno 24] Too many open files

[diver]

Probably a dup of #2820

[nielx]

Fixed again. I did not manage to extract the proper information. Something strange happens with the temporaryfile, for some reason it tries to create the file over and over again (100 times), after that, the whole process is flooded.

Sigh.

Thanks! It doesn't really make much sense to mark these bugs as fixed as long as the original problem persists, though.

The bug is also tracked at Trac: ​http://trac.edgewall.org/ticket/7611

[nielx]

It seems that the most recent software update fixed this condition. Though it needs a bit more time, I do not see the earlier behaviour, and as such I declare this fixed for now.
