I must confess I dont really understand how to implement this, and
neither know if this is something for me. I mean the kind of webapp I
have will probably not gain benefits by using this approach.

Yes I will try this too. When the exec hangs up I will try to call a
test php-script that, in turn, only calls a dummy c# app, one that
only prints hello world. If it will not help, I think I will try to
replace all my calls to exec with popen. And see if that will help...
Anyway the first thing I will do is to replace the php-copy with a
newer one(it is 5.2.1 now). Cause I reallt dont know how to face this
problem anymore. Thanks all for the help, will be back in case of
better news.
