Hi Fred,
i am using +Parent on debian lenny mpm_prefork
and on ubuntu 10.04 mpm_prefork i have hade no issues with JSON::XS
i use '+Parent' to use different Modules Versions (new versions of my
own modules) in a test environment (vhost) on the same server.
I have got some projects running with +Parent and JSON:XS in parallel,
but never got this error.
Do you use the default apache and mod_perl packages, which version you
are using?
But i have to acknowledge '+Parent' didn't work for me i some Situations.
a long time ago i tried to hold a database handle in a global package
variable
#######
package MyPackage
my $dbh;
#######
i thought it would be fine to do this with +Parent, but mod_perl didn't
separated it clearly, and things stared to become strange.
so i started to use something workarounds:
######
package MyPackage;
my $vhost_dbh = {};
sub handle{
#...
$vhost_key = $config->{'vhost_key'}
my $dbh = $vhost_dbh->{$vhost_key}
if (! defined $dbh ...
}
########
Maybe your are also relying on some globe variables in your code?
best regards keywan.

Has anyone ever used the +Parent option with their mod_perl based system?

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.
