Very high pfsync traffic

[adam.blackburn]

Hi All,

I am a bit stumped about what is going on
We have had a huge amount of data usage over the last few days and I have finally tracked it down to pfsync!

It looks like it is unicast traffic and over the last few days it has broadcast about 12TB
I've attached (hopefully it works) a screenshot showing the high usage from the insight page

Any ideas where to look and see why it is doing this?

Thank you!

This is really huge. Can you check content via tcpdump?
