pi node-red (15.2) goes 100% after a number of deploys

[Simon H]

Does anyone else find that after a few deploys (I always do a 'full' deploy), that after each deploy node-red cpu usage rises, until each deploy takes longer and longer, and eventually node-red is sitting close to 100% cpu; solved by killing it and letting it restart?

I thought it might have been gathering graph data, but I'm limiting the number of points, and the CPU seems to be ok for days if i'm not working on flows, so i'm pretty convinced it's related to deploys....

I have 10 flows, non std nodes include wemo, bigtimer (issues occurred before installation of this one), all other nodes are std (mqtt, various dashboard, function nodes, inject, etc.).

Is there an easy way to profile what's going on?  I've used node-debug on windows, but don't really fancy this on pi.  Maybe some way to dump the nodejs task queue on demand?

Any thoughts welcome.

I am not seeing increased cpu usage (that I have noticed), but on one
of my Pis every time I deploy it uses more memory, till eventually the
whole thing grinds more or less to a halt and I have to restart
node-red, if it does not crash and restart itself. I have not reported
it as the flow includes DIY charts and it may be something I am doing
that is causing the problem so I was going to do a bit of
investigation first.
