Subject: New history plot facility 
Our typical use case is that a lot of people are connected to the experiment
having some history tabs open most of the time. Hence, I setup a test system and
connect to it from all kind of systems/browsers. What I see currently quite
often is the error hs_read_arraybuffer (see the attachement).

For firefox 60.8.0esr this can result into a full freeze of the tab and only
closing it is possible.

For chromium based browsers you eventually get a popup informing that it is not
responsive anymore.

The worst though is safari 12.1.2 which not only freezes the tab, but
reproducibly crashes the mhttpd on the server side.

Are there ways to get a log which would document where the problems start?
