[jira] [Created] (TS-2395) Healthchecks plugin using 100% of CPU

David Carlin created TS-2395:
--------------------------------

             Summary: Healthchecks plugin using 100% of CPU
                 Key: TS-2395
                 URL: https://issues.apache.org/jira/browse/TS-2395
             Project: Traffic Server
          Issue Type: Bug
          Components: Plugins
            Reporter: David Carlin


I had configured the healthchecks plugin to serve four healthchecks - they come in pretty frequently, it can be hundreds per second.  Use of the plugin would peg every core to 100% in htop.  Response times for the healthchecks were often around 4 seconds.

The code from master was used to build the plugin.

perf top output showed the following:

87.74%  [kernel]                 [k] _spin_lock
