ERROR t[de8] PingChildProcess ping loop: process "wlp" is not active, so restarting it.
Recently, there was an issue with disk space. Once the disk space had been recovered, the Cognos service would not start.
Diagnosing The Problem
The contents of the cbs_run_WebSphereLiberty.log file showed that there was a problem with starting the wlp process
Resolving The Problem
Allow a new workarea directory to be created by renaming <cognos_install_location>\wlp\usr\servers\cognosserver\workarea
and then restart the Cognos service.
Due to the problems with disk space, it is possible that it caused the contents of this directory to become corrupted.
