Reboots due to heap memory - resolved

Support

How do I go about troubleshooting this error?
2/06/23 10:06:28 Heap memory has degraded below safe minimum, restarting.

I read through a few other forum threads and wifi issues seemed to be a common cause, but I doubt that’s the case here. I’ve got a pretty solid connection in a reasonably radio quiet basement.

Reboots seem to be about every 1.5 minutes or so. I’ve got it connected to Home Assistant through the Iotawatt integration.

It appears that you have at least 11 integrators configured. I believe that is what is causing heap to be depleted. Each integrator requires an open file with associated buffers.

I think you may have a misunderstanding about purpose of integrators. I think it’s unlikely that you are getting any useful result from most of them.

Integrators are used to separately accumulate the negative and positive components of an input series such as a mains input when there is a PV system that can cause energy to be exported.

For an input like a Fridge that only consumes energy, there is only a positive component and the Wh total is a monotonically increasing series. There will be no negative component and the integrated positive component will be exactly the same as what is maintained in the standard datalog.

OK, I deleted most of my integrators and there is certainly some improvement. I am no longer seeing the heap memory warning. It is still rebooting more frequently than I would expect, but now it’s every few hours instead of every minute. Updated logs are below. Are these reboots expected, or is there another problem to figure out here?

Based on your previous message I can probably delete all of my integrators except for the Total and Remainder ones. Is that correct, or is there a better way to monitor those also? My PV system is monitored in my main disconnect box by a different system, all circuits that the Iotawatt monitors should always be positive in my setup.

They are expected given the situation but definitely not normal. I did not notice that the integrator logs had very old dates on them. Some of these restarts seem to have been caused by the act of deleting an integrator. You still have at least five of them. They are not current or “synchronized” so that eats up even more resources. You should probably delete them all, see if the unit stabilizes, then add back only the integrator that is necessary.

Barring WiFi issues or power failure, the unit should only restart every six weeks.

OK, at the moment I’ve deleted all but two of the integrators. The two remaining are:
Remainder Wh = A01 + A02 - (A03 + A04 + A05 + A06 + A07 + A08 + A09 + A10 + A11 + A12 + A13 + A13 + A14)
Total Wh = A01 + A02

Maybe the guidance I was following is obsolete now. Is there a way to reproduce this functionality without an integrator?

Hard to say without knowing what these inputs are. You say that your solar is connected upstream of your mains in the main disconnect box. So, your mains should always be positive. If that is the case, you would not need integrators. The scripts that you are using for the integrators could be outputs.

I’m assuming that you are getting the solar exported to HA and are computing your import/export there.

I deleted all of the integrations and run time is currently up to 22 hours, so it looks like this has fixed it. I was also able to use outputs instead of integrators to get the information I need into home assistant. Thanks for the help.
