Now its working again.. very interesting to see what happens and that

My testing environment:

Machine: p2-233, 128 MB, pg71 from cvs

OS: FreeBSD 4.2 from cvs

This message appeared while a traffic of 160.000 hits to my server
with approx 15 connections to postgres and a lot of complex queries,
always at the same time (i like regression testings heheeh).
