Sensu UI Going Offline

Hi, I’m seeing this behaviour in 6.10.0, the webui stops listening on port 3000, there are etcd warnings about requests taking >100ms.
I haven’t correlated the time when the UI dies with the etcd warnings yet as there are no log messages from the UI backend.
Has there been a regression?
I’ll try increasing the etcd timeouts as suggested here Sensu Go WebUI Randomly Crashing · Issue #4139 · sensu/sensu-go · GitHub but with lower values. The warnings I’m getting are >100ms and <300ms
