Description

After running a stress test (with stomp-benchmark) on the latest Apollo snapshot, we get incorrect metrics via the REST API.

Most queues are empty but we get for /dest-metrics:

{
'consumer_count' => 2,
'consumer_counter' => 3747,
'current_time' => '1331811113155',
'dequeue_item_counter' => 1308687850,
'dequeue_size_counter' => '1676664197980',
'dequeue_ts' => '1331811112533',
'enqueue_item_counter' => 2903640770,
'enqueue_size_counter' => '2557292455212',
'enqueue_ts' => '1331811113155',
'expired_item_counter' => 0,
'expired_size_counter' => 0,
'expired_ts' => '1331811094462',
'nack_item_counter' => 219021,
'nack_size_counter' => 86391291,
'nack_ts' => '1331811094462',
'objects' => 12,
'producer_count' => 77,
'producer_counter' => 4838,
'queue_items' => 280614806,
'queue_size' => '236922566764',
'swap_in_item_counter' => 326917022,
'swap_in_size_counter' => '345397442494',
'swap_out_item_counter' => 610143466,
'swap_out_size_counter' => '583772449904',
'swapped_in_items' => 163303,
'swapped_in_size' => 88326399,
'swapped_in_size_max' => 819200000,
'swapping_in_size' => 1752840,
'swapping_out_size' => 1310961,
}

Note that queue_size=236922566764, so rough;y 220GB. OTOH, we see:
