Has anyone ever used the +Parent option with their mod_perl based system? http://perl.apache.org/docs/2.0/user/config/config.html#C_Parent_
Have been trying to debug an issue where this error was being encountered in JSON::XS based code with two virtual hosts, each with their own +Parent interpreter pool: panic: free from wrong pool at /My/Subclassed/JSON-XS-Class.pm I'm guessing that some code refs were still shared between the interpreter pools.
