Hi all,
I had a similar issue (frappe-bench-node-socketio: ERROR (abnormal termination)) after a vanilla install (Debian 8.7, ERPNExt v10.0) with
$ bench restart
/home/frappe/frappe-bench$ sudo bench restart
INFO:bench.utils:sudo supervisorctl restart frappe-bench-workers: frappe-bench-web:
frappe-bench-frappe-schedule: stopped
frappe-bench-frappe-default-worker-0: stopped
frappe-bench-frappe-long-worker-0: stopped
frappe-bench-frappe-short-worker-0: stopped
frappe-bench-frappe-web: stopped
frappe-bench-frappe-schedule: started
frappe-bench-frappe-default-worker-0: started
frappe-bench-frappe-long-worker-0: started
frappe-bench-frappe-short-worker-0: started
frappe-bench-node-socketio: ERROR (abnormal termination)
frappe-bench-frappe-web: started
The error trace shows (logs/node-socketio.error.log)
$ cat logs/node-socketio.error.log
Error: Cannot find module 'express'

Trying to resolve it with
$ sudo npm install express
$ sudo npm install socket.io
has resolved the issueā¦ Maybe this helps someone else
