Connection pool full - restart of HA

Installation Home Assistant OS
1

Hi guys,
Once every 3-4 days my HA-instance restarts.
First it’s get’s slow with a major CPU usage. Then this error appears. After a while HA gets restarted and it will be working for a couple of days.
HA is running internally with remote UI.
What to do?

Every 2-3 days HA restarts, same issue. New log:

19-05-23 19:37:25 WARNING (SyncWorker_0) [urllib3.connectionpool] Connection pool is full, discarding connection: localhost
19-05-23 19:37:25 WARNING (SyncWorker_12) [urllib3.connectionpool] Connection pool is full, discarding connection: localhost

I sometimes get the same thing, a reboot at 3am or something, but I’m not getting the ‘Connection pool is full, discarding connection: localhost’ error message.

Next time it happens I’ll try and save my log
