I’ve bee running under Proxmox for several months now. All in all, it works well, but I get these errors on a regular basis in the VM’s console. influxDB and the cc1plus compiler. I’ve added this to the influxDB config to disable the internal monitor
cc1plus is the c++ compiler, as you might now.
I guess you are running the ESPhome addon as well, which is the only reason I see why the C compiler would run on HAOS? My guess is also that those errors pop when your are updating (recompiling) ESP devices.
Not much you can do, really. You’re just plainly out of memory to run all the addons you want…
Maybe try to stop some addons before updating ESPhome devices…
