Hi All
I have a really weird problem with cocoon 2.1.11. My Application becomes
very slow under a load, even if it now relay heavy. A page request take
up to one Minute.
The strange point is that in another application I use exactly the same
java code and it works well.
All my request a past to a flow script and handled there. The time spend
in the flow (10 ms) is very small can not cause the problem.
With visualvm I figure out that a lot threads are blocked:

The bad point is that I have absolutely no idea what the root cause of
this is. Any help what I could check is really appreciated
Thanks a lot
