Symptoms

Output of 'top' command shows multiple instances of 'DAService' process (Gaia Software Updates Agent) that consume CPU at high level.

Cause

The script /opt/CPda/bin/DAService_script runs in the background and checks whether the process 'DAService' is running. If the process 'DAService' is not running, this script will start it.

Due to a race condition, in some rare cases, the script might detect that the 'DAService' is not running even when it actually is - and then start it again (multiple times).
