Re: a lot of connections in state "CLOSE_WAIT"
Hello,
is this list constantly growing? If you reload the WebUI do they pile up
again?
My guess would be the watermarks display is overloading the metrics handler.
If i remember correctly the WebUI keeps fetching the watermark metrics
regardless
of what page you're looking at.
Things to investigate would be whether it continues to query for
watermarks for finished
jobs, and whether requests are batched across tasks & jobs.
Regards,
Chesnay

FLINK-7368 may be the reason for this behavior.

So this /only/ happens when you select a metric? Without a selected
metric everything works fine?
Are the metrics you selected shown correctly?
Did you modify the "jobmanager.web.refresh-interval" setting? (maybe
check the flink-conf-yaml for the current setting)

Hello,
Could you tell us which browser you are using, including the version?
(and maybe try out if the issue persists with a different one)
