I have the same problem, I assume my server is not enought fast to proceed oll operations in script during 10 minuts (installation for excample). I have checked, server is doing somethign, but not just stunding.. I will try to do it with new server. Developers recomended set up in PHP confiruration limit memory - 12 mb at least insted of 8 by default. I suppose eZ ingine use much resourses and as result on old servers it works slowly.. God knows.. :)) oh.. no, Developers knows as well :))
