Observed on user cluster:

After a few minutes (~15 minutes the first time I observed this, 4 minutes the second time, the third time it went for 39 minutes) Workbench stops receiving messages from websockets. In the web developer tools, I see a steady stream of messages, which then abruptly comes to a halt.

Unlike the previous websockets bug, upon reconnecting I start receiving messages again.

Message volume here is pretty high, something like 30 messages per second. Each message is 400-600 bytes. These are mostly container updates.
