Thanks and regards, Neo [GC] Hi Neo, Are you running a really old version of Catalyst::Devel? If you specify the -r option to myapp_server.pl that was generated with a (oh, 2 years?) very old version of Catalyst::Devel it will not work right. This option clobbers your engine and sets the engine to 'HTTP::Restart'. Take a look at your script/myapp_server.pl and find the section for checking $restart The proper lines should be: if ( $restart $ENV{CATALYST_ENGINE} eq 'HTTP' ) { $ENV{CATALYST_ENGINE} = 'HTTP::Restarter'; } It used to omit the test for CATALYST_ENGINE, and ... well, that's not right :) Otherwise, it should definitely throw an error for an invalid engine being specified: $ CATALYST_ENGINE='Yourmom' perl script/myapp_server.pl Can't locate Catalyst/Engine/Yourmom.pm in @INC -J Ha! Thank you very much, this was exactly the problem! Our startup-scripts indeed seem to be abount two years old. I remember seeing a warning about old scripts once, but haven't seen them in a while and thought one of my colleagues fixed it. If I may ask a following question how to rebuild the scripts? _ I can't reproduce the old warning and either I'm too stupid to use Google or the howto is hidden somewhere in subspace...

This seems to have worked. I still get a warning about old scripts, but I think from now on it's our adminmonkeys thing (don't know how old our CPAN-modules are...).
