Hi
Relatively new to HA - about 3 weeks in.
HA Core - v2022.4.6
Synology NAS Docker install : Low-pri CPU + 2048Gb RAM assigned
Nothing too much integrated yet. Still feeing it out before I commit to a Pi4 build.
I had an issue recently during a late night session where my docker container was crashing due to memory full and then auto-restarting.
Initially I thought the issue was due to a typo in the raw config editor (as I shared here), but the next day I had a load of emails waiting for me from my NAS telling me that HA had been crashing every 30 minutes overnight.
Last night it started doing the same. Emails and I could see it fill up the RAM within 15 mins, slowly become unresponsive and then crash at about the 30minute mark. “Why is it only doing this at night?” … and then I realised what it may be.
The pattern seemed to follow an automation I have that triggers every /10 to re-activate my phone’s charger when the battery level dips below 93% but only when my calendar is set to “sleeping”.
As soon as I de-activated that Automation and reset my HA that it stopped. CPU load is back down and RAM back to reasonable numbers.
The only thing different in this automation compared to the others I have for my phone charging on/off is the use of the Google Calendar in this one automation as well as (“is_home”).
It’s weird 'cos this was one of the first automations I’d set up about 10 days in (preventing battery overcharging as my motivation to start HA)
The calendar itself seems to be fine. I followed SlackerLabs YT guide on integrating it into my HA and it updates quickly and the card on my homepage works fine too. I don’t use search or offset features in the google_calendars.yaml as I don’t do all day events there. Just as a trigger for events for tasker to automate different profiles on my phone.
Some screenshots below for reference
No-one likes to see this in the morning 
Next night and it’s happening again. RAM full for 10 minutes and counting…
After disabling the automaton and it’s still happy No emails:
Here’s the automation (edited to remove phone ID and real calendar name)
