apache2 log error

[wifi75]

hello I have problema on my rpi, after a few hours the system seems to go into shutdown ... I found many errors like this:

[Wed Aug 28 07:03:40.631266 2019] [:error] [pid 859] [client xx.xx.xxx.xxx:43984] PHP Notice: Undefined variable: LASTD_MET6 in /var/www/metern/index.php on line 57

what can I do?

[jeanmarc]

save layout configuration

[wifi75]

of course meterN 1.2.1 and 123Solar 1.8.3.3 already installed as soon as they are released.

[wifi75]

save layout configuration

do you mean that the problem is only that?
why do I sometimes find the raspberry offline ...

[jeanmarc]

Yes, that was the issue for Undefined variable: LASTD_MET
For the other question, it could be various problem check your errors log journalctl -p err -b -r to get some hints.

Ok I will send the command log journalctl -p err -b -r as soon as I get home, unfortunately the system has crashed and I can't log in remotely.

the first thing I will do is replace the microsd with a new one.

I'am not sure what's hangs your system but you have issue with Fail2Ban & Mosquitto.
You can get more details with systemctl status mosquitto and systemctl status fail2ban

[jeanmarc]

You could also check if a process eat your CPU/RAM via top, check the ram free -m and your disk space df -h
