Hi Experts,
We are having CIFS outages on our Filer environment (8.2.X 7-mode). Everything works normal if vcsan is truned off.
I am observing below erros on filer console (this filer AV was configured early, but vscan status is off currently). Like to know what could be the reason for these VCAN server disconnects?
