I am using the ping node for checking nodes to be alive. he error message:

Jan 05:52:22 - Error: spawn ENOMEM  
at ChildProcess.spawn (internal/child\_process.js:372:11)  
at spawn (child\_process.js:544:9)  
at Timeout.\_onTimeout (/root/.node-red/node\_modules/node-red-node-ping/88-ping.js:15:62)  
at listOnTimeout (timers.js:324:15)  
at processTimers (timers.js:268:5)  
is there any mode I can prevent node-red from stopping? Is the ping node not stable?

ENOMEM means it is out of memory.

What else are you running?

As an aside is there any reason you are running as root?
