child process error: Error: channel closed #238

Open RonItelman opened 8 years ago

RonItelman commented 8 years ago

I keep getting this error (using Mac OS X) so I have had to disable it. Love the plugin, hoping a fix comes soon.

More info: http://stackoverflow.com/questions/37421204/child-process-error-error-channel-closed-node-atom/37737769#37737769

Thanks!

A bit more information is needed, since this will not give me a hint what is causing the issue.

e.g:

a.s.o.

I am getting the same error when editing files that use ECMAScript 6 syntax very often. Restarting Ternjs server helps for a few hours.

I'm having the same issue.

Same issue. Or not, for me the error pops in stdout only at app shutdown.

Same issue- i'm on windows 10- on mac i don't seem to get it.

Its pretty spammy, seems to trigger almost on key up. Disabled atom-ternjs cause of it.

So it looks like the worker thread sometimes runs into a state when it can't receive messages but does not exit. The error message discussed here appears on attempt to send a message to a worked which is stuck in that state.

It may be a bug in the Server class. Or something may freeze the worker thread. It's not easy to debug.

Here is my fork with automatic restart of the worker thread on error: https://github.com/A2K/atom-ternjs/commits/master

I am not sure if it is a good solution to this problem, please tell me what you think.

I have same issue on mac osx 10.11.6

RonItelman commented 7 years ago

It definitely has been happening a lot less since your update - thanks!

m3talstorm commented 7 years ago

Starts getting really spammy, error comes up on every keypress (attempt to validate/autocomplete/etc?) filling up the screen. I my muscle memory now presses escape (to close them all) every few seconds of typing 👎
