Investigate slowness (infinite loop) when using the UI for a while

[Caleb-Ellis]

The UI can become unresponsive in production.

Steps to replicate

Switch repeatedly between any two views.

we should backport this to 2.7

I've released a new version of maas-ui with source maps enabled, which should hopefully help us debug this. Awaiting a new maas release so that this can be tested on bolla.

Some relevant angularjs discussion.

It appears we have a leak.

The result of switching repeatedly between Machine List and Machine Details over a 10s period.

This can be replicated by switching between any two views afaict however, and isn't specific to the machine list or details views.

Looking at the heap profile, we appear to have a large amount of detached nodes.

Not a V8 specific issue, the leak exists in Firefox as well.

Kit, was there a fix delivered or is this a bug we are willing to live with? I don't see a solution comment.
