Julia 0.7.0: Random Messages in REPL


#1

Hi,

I updated to Julia 0.7.0 and is seeing some random debug kind-of messages in REPL. They don’t occur often. If I keep the REPL open for a few hours, these messages appear (randomly).

$ julia

To reproduce:
Just start julia REPL and keep it for a few hours.

I’m observing this in Elementary OS 0.4.1 (Ubuntu 16.04 based).

Any thoughts on why this is happening??

Thanks,

That’s a weird one, but the messages are definitely originating from outside Julia, see for example this issue. Is anything else running that’s attached to that particular terminal?


#3

What terminal are you using? This looks like an error with GNOME shell. See the following AskUbuntu post for an example: https://askubuntu.com/questions/1045214/ubuntu-freezes-desktop

Oops… Seems like some problem with my shell.

I restarted shell and kept julia open for 10hrs now, and there are no problems.
