"Thermal sensor interrupt received" and "Event(0x5c000001)" , error code reference

Hi

We are getting a lot of these errors on a stack of M4300 switches:

<10> May 22 12:35:17 DEVICE1 DEVICE2 General[intDisTask]: cpu_boxs.c(2197) 36702 %% Event(0x5c000001)
<13> May 22 12:35:17 DEVICE1 DEVICE2 BSP[intDisTask]: cpu_boxs.c(2194) 36701 %% Thermal sensor interrupt received on the unit 1

These messages are logged many times in quick succession seemingly at random times and days. The temperatures are normal.

I cannot find information about these errors, does anyone have a reference for  Event(0x5c000001)  or any advice what we can do to fix this issue? We dont see any issues on the connected clients (yet).

Thanks
