Lots of output: [overseer master] proxy signal (urgent I/O condition) #43

Closed kokizzu closed 4 years ago

kokizzu commented 4 years ago

It seems it always outputting those lines every few seconds, is there any meaning about this? or is it because my VPS using OpenVZ?

There's another process signalling your go process. Maybe this is a feature of your VPS? telling you to slow down your IO?

Interesting, if you can make a reproducible example, I can take a look at it

Ah nevermind, i think i know the problem, i set the ExecutablePath to wrong file.

jpillora commented 4 years ago

@kokizzu are you using a flavour of BSD (includes Mac OS)?

I just did some testing and saw this in the debug logs. Last time I tested, was before the Mac OS Mojave, so I'm guessing this is a change with the OS. Looks like you can safely ignore it anyway

kokizzu commented 4 years ago

Nope, I'm using Ubuntu 18.04.4

jpillora commented 4 years ago

Update: it's a change with go 1.14 https://github.com/golang/go/issues/37942
