GT-AX11000 Crashing - Syslog

My GT-AX11000 (running merlinwrt 386.4) has been exibiting random crashes/reboots several times a day, intermittently. Some days more than others. Some days may be reboot free. Today (1/20/22) was the most egregious at 5 reboots in total. mind you these reboots are not new to 386.4, ive had them in all previous firmware iterations.

I have two AC68Us in AP mode connected by ethernet backhaul, and are also running the same firmware.
I have approx 74 clients at a time.

Pastebin of most recent crashes https://pastebin.com/RnU3XsrM - the dates appear to be out of order

I have had my AX11000 (A1.1) for just over 2 weeks w/o any issue. I have also dirty flashed it with Merlin 386.4 and the latest 2 official FWs back & forth w/o issue. It misbehaved once because I was toying with the settings too much and a hard reset fixed it. Though not related to this router, I had PCs reboot themselves due to overheat in the past. Maybe you can observe the temperature in Merlin and see if it's related.

its not temps - i have two fans under it, and its reporting the following

Legend: 2.4 GHz - 5 GHz - CPU
Current Temperatures: 36 °C - 36 °C - 44 °C

im gonna try switching to AiMesh mode (Ethernet backhaul), as opposed to AP Mode on both my AC68U's - and see if that makes any difference. then ill also try binding them to their respective closest AP, or adding them to the roaming block list.
