hmm.. this problem with "broken pipes" only occur when there are too
many concurrent accesses to a CGI script, which communicates to
another application.
but, the system only freezes when we stop and re-start the webserver.
so, could be this CGI script causing all the trouble (by starting and
dying and leaving traces/ perfoming this "load pattern") ?

no, it's not Rev. B. we wanted to use it but we had some compatibility
