Wrapper shutting down XLD with "ping between java application and wrapper timed out" Error

Follow

Shashank Srivastava -

Issue

Sometimes, XLD seems to have shutdown itself without any obvious reasons when it is installed as service.

Environment

XL-Deploy

Resolution

Increase the value of "wrapper.ping.timeout" property in "xld-wrapper-linux.conf" or 

"xld-wrapper-win.conf" file, uninstall the service & reinstall the service. Default value is 30 seconds, so increase it to a reasonable value like 120.

Cause

This happens when XL-Deploy application is not able to communicate with Wrapper because of high load. Wrapper continuously pings XL-Deploy application and if it doesn't get a reply back from XL-Deploy, it shuts it down.

Additional Information

Below error is seen in logs.
