Somebody can reproduce it?

[yohanyars]

Sometimes os.cpus() returns undefined.

Thx the info.

[yohanyars]

Error is not fixed.

Context:

Moleculer version: moleculer@^0.13.3

Try this example:

try {
   setTimeout(function () {
      a.map(function () {})
   }, 5000)

} catch(e) {
   console.log(111); 
}

@faeron it's true. The outer try...catch can't catch the setTimeout callback errors. Could you fix it?

[faeron]

Yes. I catch the errors now seperately for each timeout.
