After the latest update, Dirac still works fine, but opening a large file in the Sources panel almost immediately causes this:

Default DevTools panel still works fine with the same large file.

@p-himik try to open intenal devtools on Dirac DevTools window to potentially see some errors: https://github.com/binaryage/dirac/blob/master/docs/faq.md#something-broke-how-do-i-debug-dirac-devtools-frontend

The file bokeh-0.12.11.js that I'm trying to open is 44k lines long.

Compiled cljs/core.js also causes this.

unfortunately from the messages it is not clear why the connection was lost, I expected some error message before Connection is closed...

@p-himik if you fork dirac-sample or create a standalone repro project I would look into that

Yeah, I'll try.

otherwise I will probably just wait, this is likely some devtools issue

one thing you could try is to enable "Pause on caught exceptions" in the internal devtools debugging Dirac DevTools and reproduce the bug, it could stop at some exception which would tell us some other location...

have to go, good luck

also try to update your chrome to ~65.0.3283+

I'll wait for it then - the latest available for Ubuntu is 64.0.3278.0-1.
