HA keeps becoming unavailable/crashing

home assistant keeps crashing. i won’t be able to connect to my home assistant. i have to stop and restart the VM in order to get it running again. Any way for me to track down what may be causing this?

You post so little information that nobody will be able to helps you.

What kind of HA installation is it?
Did you understand the installation process or did you followed a step-by-step guide or video?
What do you mean exactly by “crash”?
Do you have to restart the VM because it’s deadlocked or because you don’t know how to restart HA otherwise?
What did you try already?

HA becomes unavailable on my network. it may still be firing things in the background, like automations. sometimes. but then i usually have to restart the VM machine to get everything working correctly again. I think it may be that there was 1gb RAM assigned to it for the VM. I’ve increased it to 4. I’ve been doing a lot of automations lately and am wondering if it was reaching it’s limit.
