Error on tsserver startup: "JavaScript heap out of memory" #743

Closed huljar closed 4 years ago

Hi all,

recently the tsserver that is started through the plugin crashes a few minutes after starting Sublime with the following errors on node's stderr:

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
 1: 00007FF638AC879A v8::internal::GCIdleTimeHandler::GCIdleTimeHandler+4506

Is there anything I can do about that? I am working on a relatively large project and it seems like some recent commits caused the tsserver to exceed its memory limit when building. On Sublime's console, this resulted in the error message as in #696.

Thanks!

Hi everyone,

I was able to solve the problem by adding

"node_args": ["--max-old-space-size=4096"]

to my Preferences.sublime-settings to increase the maximum heap memory size.
