How is your database server accessed by the webserver? If it's running as an application that apache accesses directly (eg, CGI or similar executes DB queries) then a DB error should cause the script to fail and a "real" 500. However, if the DB is an HTTP-aware back-end and is accessed via mod_proxy then the 500 is generated in the DB server and is simply passed on by apache. So it's not a 500 in apache, hence no error log. I suspect the latter since you mention an "Operational Error" page that, presumably, comes from the DB server. > > If I shut down my app servers, I can simulate/cause an 502 error fine > and the 502 error page I've created displays fine, and I get a message > like this in the error log: > > [Tue Apr 17 07:45:06 2007] [error] (111)Connection refused: > proxy: HTTP: > attempt to connect to 127.0.0.1:9999 (localhost) failed Sure - apache can't connect to the DB so it is apache that has to report back to the client. Hence error logging. > > Can anyone enlighten me? Did I?
