I have run several tries and the one that could get me over the 2 days stability issues was running the recorder running with sql in memory (which of course has the disadvantage of all stats being gone at restart).
The following stabilized my environment
- uninstalled Maria DB and let system run with default db
- added scan_interval: 180 to platform: systemmonitor to reduce the number of database inserts related to the health of the system (default is 15 seconds so bumped up to 180 s)
- change purge_keep_days: 7 (I could not even run with 2 in MariaDB)
System is quick and stable and the sql db is at 25Mb after 2 days.
Maybe is the MariaDB integration that de-stabilized my system or the recorder link with MariaDB.
I will post my status at the end of this week after the purge kept the database to 7 days of events.
Hope that helps.
