Logstash found only one occurrence:

http://logstash.openstack.org/#/dashboard/file/logstash.json?query=message:%5C%22hasn%27t%20been%20spawned%20in%2020%20seconds%5C%22

Perhaps it was just a transient error?

[Matt Riedemann (mriedem)]

I just hit this in the gate:

http://logs.openstack.org/83/465783/1/gate/gate-neutron-dsvm-functional-ubuntu-xenial/14d985e/console.html#_2017-06-15_05_40_16_809140

but yeah it definitely doesn't show up much:

http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22RuntimeError%3A%20Process%20%5B'ping'%2C%20'192.168.0.1'%2C%20'-W'%2C%20'1'%2C%20'-c'%2C%20'3'%5D%20hasn't%20been%20spawned%20in%2020%20seconds%5C%22%20AND%20tags%3A%5C%22console%5C%22&from=7d

2 hits in 7 days.

A rare failure, but still happens: http://logs.openstack.org/57/493057/11/check/gate-neutron-dsvm-functional-ubuntu-xenial-nv/79674c0/console.html

[Slawek Kaplonski (slaweq)]

No hits in last 30 days. I will mark it as incomplete for now. If You will spot this issue again, please reopen it

[Slawek Kaplonski (slaweq)]

Ahh, and link to logstash: http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22RuntimeError%3A%20Process%20%5B'ping'%2C%20'192.168.0.1'%2C%20'-W'%2C%20'1'%2C%20'-c'%2C%20'3'%5D%20hasn't%20been%20spawned%20in%2020%20seconds%5C%22
