Subject PIO deploy: old processes still live after redeployment
Date Fri, 06 Apr 2018 01:43:00 GMT
Hi everyone,

I faced a strange situation recently.
One of our engines has frequently old processes after daily redeployment.

We used to redeploy by crontab rule that looks like:
nohup pio deploy --port 8004 >> ${DEPLOY_LOG_FILE} 2>&1 &


This is output of ps aux command:

[da_mcom_milan@mdc2pr113 ~]$ ps aux | grep 8004

da_mcom+  7854  0.0  0.0 112660   996 pts/1    S+   21:34   0:00 grep

For some reasons, processes 30932 and 31097 still alive and process
listened by 32671
Any ideas?

Thank you,
George
