Very high CPU usage caused by [VFSDir] failed to walk dir with path

XMLWordPrintable

    • Sprint candidates, S2401-2
    • 3

      Steps to reproduce:

      1. Upgrading from zabbix-agent2=1:5.0.18-1+bionic to zabbix-agent2=1:5.0.20-1+bionic

      Result:
      See screenshot...

      Lots of error saying : "[VFSDir] failed to walk dir with path /some_path/somewhere"

      CPU usage goes up to 100% and stays between 95% and 100% all the time

      I had to stop the zabbix-agent2 service until this issue is fixed, it renders the system unusable !

      Expected:
      No error, no extra CPU usage

      This behaviour didn't exist with the 5.18 version of the agent.

      After yesterday's update, problems started to arise...
