Hi all,
I’m pretty new to HA, so apologies for any inexperience. I currently have HA running in Docker on my Synology NAS. It is a pretty old DS216+II with just 1 GB of RAM.
I have added a few integrations and basically everything runs fine. However, from time to time, the HA frontend (and core?) becomes completely unresponsive for several minutes at a time. Afterwards, without any container restart, everything’s fine again. I have disabled all integrations that produce errors or warnings so that the log is basically empty and doesn’t provide any help.
The NAS is fully responsive during these “freezes”. I have captured a screenshot from the Resource Monitor when the issue had occurred most recently:
What is noticeable is the high value for I/O Wait when looking at the CPU utilization. It’s hovering between 50% and 80% whenever the issue occurs.
Any ideas to narrow down the issue? Is my NAS simply too old and slow to run HA in Docker?
