[p2-dev] http instabilities

["Haigermoser, Helmut" <Helmut.Haigermoser@xxxxxxxxxxxxx>]

Ciao P2 :)
We recently had a surge of problems updating our products, using
standard p2/ecf technologies,
I'm hoping you've seen these and can point us at options to tweak the
bevaviour to get by such issues...

Here is the backtrace for our 3.5-based product:
