Description of problem: qpid-stat -q returns an unexpected high value in the 'msg' field Version-Release number of selected component (if applicable): qpid-tools-0.18-10 How reproducible: random Steps to Reproduce: Originally QueueBrowser in the EAP6 JCA framework with local transactions was tested. As the test was running I was checking the status of the queue using qpid-stat -q (the output i in the Actual results section) 1. Message Driven Bean is reading messages from mrg_localtx_ha_in and redelivers them to mrg_localtx_ha_out 2. in a loop, QueueBrowser is checking how many messages are present in mrg_localtx_ha_out Please also note, that there is a fault found in QueueBrowser (which I believe is a separate issue) which moves messages from msgIn to msgOut. Normally in this scenario, no mesages should be removed from mrg_localtx_ha_out by QueueBrowser. Actual results: If I issue qpid-stat -q several times while client is working vhubeika @rhel6i /root $ 15:47:24 # qpid-stat -q Queues queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind ========================================================================================================================== f2cd02b4-56f5-4395-8fff-9b8ded5a7c74:0.0 Y Y 0 0 0 0 0 0 1 2 mrg_localtx_ha_in 485k 501k 15.7k 13.0m 13.4m 395k 0 1 mrg_localtx_ha_out 166 15.7k 15.5k 6.51k 395k 389k 0 1 vhubeika @rhel6i /root $ 15:54:14 # qpid-stat -q Queues queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind ================================================================================================================================= b4bf96f8-41d0-4fb7-a902-fe30eb1fe626:0.0 Y Y 0 0 0 0 0 0 1 2 mrg_localtx_ha_in 485k 502k 16.2k 13.0m 13.4m 411k 5 1 mrg_localtx_ha_out 18446744073g 16.2k 16.3k 397 411k 410k 0 1 vhubeika @rhel6i /root $ 15:55:15 # qpid-stat -q Queues queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind ========================================================================================================================== f20a5c78-0ab9-4b8e-a561-c31355ece387:0.0 Y Y 0 0 0 0 0 0 1 2 mrg_localtx_ha_in 485k 502k 16.5k 13.0m 13.4m 417k 5 1 mrg_localtx_ha_out 11 16.5k 16.5k 2.48k 417k 414k 0 1 0 1 vhubeika @rhel6i /root $ 15:55:20 # qpid-stat -q Queues queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind ========================================================================================================================== 71178b53-f26d-4511-a396-27a46688a0da:0.0 Y Y 0 0 0 0 0 0 1 2 mrg_localtx_ha_in 485k 502k 16.5k 13.0m 13.4m 418k 5 1 mrg_localtx_ha_out 56 16.5k 16.5k 3.65k 418k 414k 0 1 0 1 vhubeika @rhel6i /root $ 15:55:21 # qpid-stat -q Queues queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind ================================================================================================================================= a534c008-33a3-47f3-9a78-56ef40ca8065:0.0 Y Y 0 0 0 0 0 0 1 2 mrg_localtx_ha_in 485k 502k 16.6k 13.0m 13.4m 420k 5 1 mrg_localtx_ha_out 18446744073g 16.6k 16.7k 553 420k 420k 1 1 vhubeika @rhel6i /root $ 15:55:26 # qpid-stat -q Queues queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind ========================================================================================================================== afb199c6-e2e4-40c8-90b2-e40b448acfe1:0.0 Y Y 0 0 0 0 0 0 1 2 mrg_localtx_ha_in 485k 502k 16.7k 13.0m 13.4m 422k 5 1 mrg_localtx_ha_out 9 16.7k 16.7k 2.42k 422k 420k 1 1 1 1 vhubeika @rhel6i /root $ 15:55:29 # qpid-stat -q Queues queue dur autoDel excl msg msgIn msgOut bytes bytesIn bytesOut cons bind ================================================================================================================================= 78fb51aa-8d7a-4e18-af52-cf95d722384c:0.0 Y Y 0 0 0 0 0 0 1 2 mrg_localtx_ha_in 484k 502k 17.7k 13.0m 13.4m 448k 0 1 mrg_localtx_ha_out 18446744073g 17.7k 17.7k 1.72k 448k 446k 0 1 also if I check the status with qpid-tool i see that msgTotalDequeues is larger than msgTotalEnqueues !
