Thanks for the tip! I investigated the log, and found a LUA script that would run more than 10 seconds occasionally. This script tried to pull devices from a roomplan. I replaced this script by one that simply has an array of device names, and it now runs quickly and does not run long.jvandenbroek wrote: ↑Wednesday 20 September 2017 15:10Are you sure there are no errors in de log which might indicate that Lua scripts never finishes? Something like "warning script took more than 10 seconds to execute", it's not guarantied that they will ever finish (thus holding the allocated memory). I suppose you could test it easily by temporary disabling all Lua scripts and see what happens in a few hours. 8 to 10% is way too much, my experience is that it will almost stay the same after a few min after starting up.
@manjh I now see that you're not the TS. You mentioned rebooting the Pi, but then we don't know if it's Domoticz causing the climb. Does restarting just Domoticz result in the same dip? In that case, try what I said above (disabling Lua).
Result: memory is now stable at about 6%!
I am happy now......
