Why did pcsd daemon crashed during nessus scan - and how can I prevent it from happening again?

Solution In Progress - Updated -

Issue

  • Security audit was performed on cluster nodes through nessus tool for security audit. As a result of nessus scanning, pcsd cluster status shows offline:
PCSD Status:
  node41: Online
  node42: Offline
  • The pcsd appeared to hang or crash when doing a scan with "Nessus scan tool" and the following was logged in the file /var/log/pcsd/pcsd.log (where X.X.X.X is an IP address):
