New worker seems to have failed to start on Ubuntu 16.04

Hi

I'm trying to run server_starter in Ubuntu Server 16.04, and I'm receiving this message:

new worker 4397 seems to have failed to start
starting new worker 4402
new worker 4402 seems to have failed to start
starting new worker 4406
new worker 4406 seems to have failed to start
starting new worker 4410
new worker 4410 seems to have failed to start
starting new worker 4414
new worker 4414 seems to have failed to start
starting new worker 4418
new worker 4418 seems to have failed to start
starting new worker 4427

It occurs infinitely, and only stops when I kill application pid.
Do you know what can be the problem?

My Go version: 1.12
Command executed: $GOPATH/bin/start_server --port 6001 --pid-file app.pid -- ./app &
It's an API developed with echo

Thanks in advance
