in thread JSON::XS and blessings

That sounds like you're deploying binaries, not building them in situ. I would try installing JSON::XS manually on the problem server in a different directory maybe and comparing the resulting code libs with what's already there. Or, if you can safely do destructive testing, just install it manually in the same place and see if the problem clears up.

    I built it myself, not deploying binaries This ubuntu server came naked, and I installed apache, mod_perl and all the cpan modules I use including JSON (and JSON:XS).

    If JSON:XS did not work, it would have been an easy thing to fix. If it does work in one virtual server and not on the other (running on the same machine, same apache server), that may push one to believe in ghosts.

      :P Heisenbugs happen… they are, by nature, not repeatable.

        Haha, yes. Except that in this case it's totally repeatable. One virtual server always has a live cat, the other always has a dead cat.
