It's definitely the same as Milan's from my point of view. Many thanks for reporting it as well. > Willy, are your patches "production-safe" (meaning it is reasonable enough > to run it a few hours in production) ?

I'm even reasonably confident that they should fix the problem. You need to apply them on the latest 1.8 git maintenance version (in which case you don't need the first one which is already merged). > I can reproduce the issue quickly (~ 2 hours to be sure) on my side to help > ! That could be great! Thanks! Willy
