Errors/Slowness when transferring over ethernet

After transferring more files I'm running into the issue again today. I started transferring a bunch of photos, noticed the slowdown, checked my syslog and these entries started popping up:

Is my setup really that unique that no one's run into this issue or at least these error messages before?

I ran omv-firstaid again, used the #6 option. I got a bunch of messages like: The RRD file '../cpu-0/cpu-idle.rrd' contains timestamps in future. Do you want to delete it?

So I delete all of them. Run first-aid again and all of those filenames show up again like the firstaid program isn't actually deleting the files.

Then I check my time on my OMV VM. It's correct. Then I check the time on my ESXI server, it's a few hours behind. I change the time so it's correct. Run firstaid again, still get the same files I'm asked to delete. Run the command again with sudo eventhough I'm already root, same files come up.

Here's the related syslog files:

The line that really stands out to me is the "rrdcached plugin: rrdc_stats_get failed with status -3."
