Miniserver Low Memory - is this the same as utilisation?

[Simon Still]

I've never seen this before but I've had a 'low memory' message yesterday.  I've just spent an hour cleaning up my config - deleted all the unused/unconnected bits of code I'd got in there (things I'd superseded but kept in case I wanted to revert), a load of VI's I'd set up and not used, updated the last few lighting blocks 

But I just got the message again.  I don't think my config is large or complex compared to many peoples - it's a smallish 3 bed house.

The Minserver in Config shows as 7% utilisation - that's CPU/System memory isn't it?

Any thoughts?

Do you have any PicoC programs? Most times I've had memory low reboots it's due to forgetting to free() something (most often, the string returned from httpget)

Hmm.  no PicoC programmes but I was messing with some HTTP commands for my Yamaha receiver the other day - I've got a VI in my config with a press for on and a double press for off.  I tried duplicating that and changing 'on' to 'toggle' but it didnt' work .

All cleaned up and deleted today along with a load of other commands that didn't seem to work on my model.  (just using on and off now) 

So will be interesting to see if it happens again.

I actually ran into something similar about 2 months ago.   Random reboots due to "low memory".   I literally hadn't changed anything in the program for months, but all of a sudden I started seeing reboots, typically preceded by the NIC flapping.

I tried cleaning up, updating, etc but had no luck resolving it.   I filed a ticket with Loxone and they suggested the SD card was likely failing, even if diagnostics showed everything was ok.

I had planned on upgrading my MS, so I did that instead of trying a new SD card. Once migrated to the new MS everything worked fine, suggesting either the SD card or the old MS itself was failing.

I got a 'worn card' message yesterday but I *think* it was after I'd put the new card in (lexar 633x rather than a Loxone card).  I've rebooted again and haven't had anything since so looking like the low memory was the SD card getting old.

I'm pretty sure this will be the second replacement so getting about 5 years out of a card.
