Description

When paging and many messages in a queue, the following is observed:

$ bin/artemis producer --user admin --password admin --url tcp://localhost:61616 --message-count 10000 --message-size 10240 --destination queue://FOO
...
$ curl -XPOST -H "Content-Type: application/json" -H "Origin: http://localhost" --user "admin:admin" -d '

{"type":"exec","mbean":"org.apache.activemq.artemis:broker=\"0.0.0.0\",component=addresses,address=\"FOO\",subcomponent=queues,routing-type=\"anycast\",queue=\"FOO\"","operation":"moveMessages(int,java.lang.String,java.lang.String,boolean,int)","arguments":[500,"","DLQ",false,500]}

'
...
{"request":

{"mbean":"org.apache.activemq.artemis:address=\"FOO\",broker=\"0.0.0.0\",component=addresses,queue=\"FOO\",routing-type=\"anycast\",subcomponent=queues","arguments":[500,"","DLQ",false,500],"type":"exec","operation":"moveMessages(int,java.lang.String,java.lang.String,boolean,int)"}

,"value":8630,"timestamp":1718395680,"status":200}

Note that the messageCount for the moveMessages operation was 500, but in reality 8630 messages were moved (verified with queue stats). This does not seem to happen for queues with a low queue depth.
