Bug #21209

failed to load all processes page, net::ERR_FAILED

Description
We had reports of workbench occasionally failing to load content when under load. I recently saw a "failed to load process list" error and the browser console suggests that it is net::ERR_FAILED (which I am guessing is a TCP connection error?) instead of a HTTP error.
I'm wondering if either:
a) a connection that was thought to still be live with HTTP keepalive or HTTP/2 session actually wasn't, and that error pops up to the browser level
b) the number of sockets the load balancer can have open is much too low, or a CORS preflight check didn't go through
On further examination, it seems that net::ERR_FAILED is a generic error that can be caused by various reasons -- but it is still notable that it isn't a HTTP response.
- Status changed from New to In Progress
- Description updated (diff)

I realize this isn't an actionable bug report so I'm just going to close this.
