SSHKit::Runner::ExecuteError: Exception while executing: npm exit status: 254

Hi,

I have been getting intermittent npm install errors during my capistrano deploy process. I'm getting back npm error code 254, which is a bit cryptic as I can't find much info about it online. This is the capistrano failure error when deploying with --trace:

Tasks: TOP => deploy:updated => npm:install
The deploy has failed with an error: Exception while executing as deploy@xx.xxx.xx: npm exit status: 254
npm stdout: Nothing written
npm stderr: Nothing written

Any ideas on why this is occurring? Thanks!

Started to get a similar issue out of the blue:

`cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy@xxxxx.com: npm exit status: 1
npm stdout: Nothing written
npm stderr: Nothing written

SSHKit::Command::Failed: npm exit status: 1
npm stdout: Nothing written
npm stderr: Nothing written

Tasks: TOP => deploy:updated => npm:install
(See full trace by running task with --trace)
The deploy has failed with an error: Exception while executing as deploy@xxxxx.com: npm exit status: 1
npm stdout: Nothing written
npm stderr: Nothing written
`

Any ideas what it could be?

Add the lline below in deploy.rb and you will be able to see detailed log:
set :npm_flags, '--production' # default

Happens when you have an out-of-resources condition on your server....like low or no processing power or ram...for processes you are currently running...this forces the connection to be closed...can be fixed by creating a swap on your server...
