Why pondering on a better solution, how do I increase the node.js memory?
Why pondering on a better solution, hod do I increase the node.ja heap memory ?
Firstly check how you are starting up Node-RED. If it has a memory (old-space) parameter on the startup, take that off so that node.js can fully manage its memory itself.
Other than that, trying to micro-manage the heap is generally a waste of time, node.js is very good at managing its own memory.
I see that you are using SQLite so that would be something obvious to check. Has the db exceeded what will easily fit in memory?
Other things you can look at are reviewing your flows for unnecessary things. Common issues can arise from over-use of sub-flows (each use creates a new instance of all of the nodes in the sub-flow) and having lots of nodes with 2 or more wires out of the same output port of a node (which forces node-red to CLONE the msg data multiple times).
Thanks for the reply.
How do I check my sqlite data length because to be honest, I have very lengthy data tables in my database
Assuming that they are written to the filing system, you can simply check their file size. I expect there are admin statements as well but Iām afraid that my SQL is very rusty.
Okay thank you
Hi Colin, observing memory usage by node js I noticed it start at 200mb during program startup and sums up gradually and eventually crashes when it goes above 2gb. Thatās after some few hours of run.
Are you using charts in the dashboard?
Hi Baknan2.
No I donāt have any charts on my dashboard
Since you can see the amount increasing over a fairly short time, I suggest disabling sections of the flows until you find which section is causing the problem.
