"File - failed to get objectId" in hostd logs

I've been looking though the logs on my ESXi 6.5 servers with vRealize Log Insight and I noticed that two of my hosts (of 16 total) show errors like the following for different VMs a few times a day. Is this something I need to be concerned about? I haven't been able to find anything by searching by any parts of any of the error messages, but since it seems to be limited to just two hosts i'm thinking there has to be something wrong somewhere, even though operationally I haven't noticed any issues or have had any reported by any of my users.
