CRS125 mirror stops working over time

I have a CRS125-24G-1S-RM
I have ports 1-23 set up to mirror all ingress to “mirror0”

I have mirror0 set to port 24

It works great for between 12 to 48 hrs and then stops.
the switch works … but no mirrored traffic at all

rebooting the switch fixes it and it works again for another 12 to 48 hrs.

running v6.23 on it.

I replaced a 12port D-Link managed switch … I need the port mirror to work.

help!
