Firewalla Blue Out of Memory

Hi,

Over the past few days, I've been losing internet connection through my Firewalla Blue. It'll generally come back after 15-20 minutes, but it's extremely disruptive to work. I know it's not my router or modem, because I can still go directly through my router to the internet. Power cycling the firewalla also helps speed things up.

I looked into the Firewalla logs, and I see oom-killer taking action at the times I've lost internet.

Dec 9 11:13:53 localhost kernel: [179775.053666] flock invoked oom-killer: gfp_mask=0x14080c0(GFP_KERNEL|__GFP_ZERO), nodemask=(null), order=0, oom_score_adj=0

This only started recently (in fact, Dec 9). I haven't added anything to the network, or changed any configurations in ~6 months. I'm using overlay mode, with an Eero Pro 6. My Firewalla Blue is on Stable Release 1.48 (96). 

Any ideas?
