Hi Mani,

Thanks for getting in touch. Clock.pfa is a file used by Octopus and Tentacle. We don’t create these audit events ourselves, but we might be checking whether the file exists before creating it, or we might be deleting it, which could trigger the audit event due to the way security auditing has been configured on your system.

Hope this helps,



Thanks so much for responding! The tentacle is running as the “Local System account” and the Local System account owns and has full control of this file. The audit event still keeps getting created. Would you possibly have any more leads?


Hi Mani,

Thanks for the reply. There’s not much we can do; Octopus needs to access files. It looks like auditing has been turned on a very high level on your system and that’s why you’re getting the events.

As an example, go to Local Security Policy, go to Audit Policy, and find the Audit Object Access policy. Change it to audit success/failure messages, then try to do anything. The security event log will fill with errors about opening files. The solution would be to turn the policy off.
