i am running a debian on compute enginge for over 3 years.
vpnserver + website (base on wordpress + database). i had 2 time windows when the instance was constantly freezing.
1 year ago - i discovered that shuttting down apache2+ sql helps to keep the isntanace live
NOW - it keeps freezing.
That the freez means for me:
1/ On google cloude the instanace is up and running
2/ Services on the instance are not available:
- ssh not responding
- website not responding
- vpn server down not responding
- i can ssh to the machine even from google cloud console.
logs on https://console.cloud.google.com/logs are dead just after the freez. Last entry in the logs wasDEFAULT 2025-02-26T08:39:02.429336545Z [resource.labels.instanceId: debian] 2025-02-26T09:39:02.428739+01:00 debian systemd[1]: Starting phpsessionclean.service - Clean php session files...

The freez is in line which the memory peak and now after the peak it is stable and working without restart
