Description

I observed that after artemis went into paging for the 2nd time, OpenWire clients were not able to read messages from their corresponding addresses. Restarting the applications connected as clients does not fix the issue. Restarting artemis, however, does fix the issue.

Both images attached show the messages of two queues.

• The upper (orange) line in the 1st graph shows count of messages in a queue to which core clients are connected.
• The lower (blue) line in the 1stg raph shows count of messages in a queue to which OpenWire clients are connected.
• in the 2nd graph, the upper (violet) line shows count of messages in a queue to which core clients are connected.
• in the 2nd graph, the lower (green) line shows count of messages in a queue to which OpenWire clients are connected.

I have a heap dump that we could share, showing the accumulated objects. the dump is about 90 MB in size If this would be helpful to have, please let me know.
