[collectd] perl plugin question: perl_read: Assertion `my_perl != perl_threads->head->interp' failed.

[Andreas Schuldei]

I reduced my plugin to this:

package Collectd::Plugins::Biosmart;
use strict;
use warnings;
use Collectd qw( :all );
my $host = "192.168.2.53";
plugin_register( TYPE_READ, 'Biosmart', 'biosmart_read' );

sub biosmart_read {
    my %v = (
        time     => time(),
        interval => 60,
        host     => $host,
        plugin   => "biosmart",
    );

    my $content;

    my $line_number = 0;
    my @content_lines = split( /\n/, $content );
    foreach (@content_lines) {
        my $line = $_;

        $v{'type'}          = "absolute";
        $v{'type_instance'} = $line_number;
        $v{'values'}        = [0];            # default value
        plugin_dispatch_values( \%v );
    }
    return 1;
}


And i get this:

sudo collectd -T
collectd: perl.c:1952: perl_read: Assertion `my_perl !=
perl_threads->head->interp' failed.

Obviously I stripped out most of the functionality, but the error is the
same for the complete plugin.

How can i solve this?

this is the config file:

sudo egrep -v '^\s*#|^$' /etc/collectd/collectd.conf
FQDNLookup true

WriteQueueLimitLow   800000
