Antonio Gallardo updated COCOON-2031:
-------------------------------------
Status: On Hold (was: Open)
Hi Sebastian,
The issue seems to be a race condition that was fixed in 2.1.10: (taken from
http://cocoon.apache.org/2.1/changes.html )
"XSP block: Fix regression introduced in 2.1.8 that under specific
circumstances logicsheets were not applied, leading to compilation errors. This
manifested itself only if a) two XSPs referred to the same custom logicsheet by
a relative location path, b) the custom logicsheet used another logicsheet, and
c) the built-in logicsheet's namespace was not mentioned in xsp:page. The
compilation errors occurred always when calling the second XSP for the first
time. Fix also race condition which could lead to similar XSP compilation
errors under high load when accessing the same logicsheet for the first time.
Committed by AN."
Let us know if just moving to cocon 2.1.10 fix the issue.

> Once i´ve already said this, that this error occurs at a different XSP as
> before. Why ever. Futhuermore, as soon as this error appears, it seems to be
> that cocoon will turn off his intern compiler, so that following XSP Sites
> which was at this time still not visit(and so not compiled!) can not compiled
> by cocoon anymore until cocoon restarts.
> I don´t know, what this is, but i still believe, its possibly that this error
> can be a bug of cocoon.
> Can anyone help ?
