Forum OpenACS Q&A: Re: fastpath / request-processor weird behavior after OS upgrade

btw, /xotcl/version-numbers returns 500 Server Error also.
What happens, if you deactivate fastpath?
ns_section "ns/server/${servername}/fastpath"
    ns_param   cache  false
do you have mmap defined? see: http://panoptic.com/wiki/aolserver/Annotated_AOLserver_Configuration_Reference
ns_section fastpath and mmap were not defined, so I added these, turned off and restarted, resulting in no change to symptoms.
I've also grepped for fastpath in the db and code.. nothing appears to be different from a standard install.

debug is now set true in config.tcl, so hopefully more info will come from that.
