Polyinterface crash with: Fatal Python error: Cannot recover from stack overflow.

[jimboca]

This looks like polyinterface was trying to handle and error but got stuck in a recursive call? The node server had been running for a long time, and no issues in the nodeserver log.

What version are you using? 2.0.29 has config change to explicitly stop this type of propagation.

[jimboca]

I should be on the latest but I'll have to check

[jimboca]

I'm on 2.0.28 which is the latest released version. https://pypi.org/project/polyinterface/ so hopefully it is fixed in 2.0.29.

[firstone]

Actually, the fix was done in 2.0.28.
8b282e2

The line 57 is what stopped propagation at least in the case that I've seen.

Is this new error frequent and/or reproducible?

[jimboca]

It's only happened once that I have noticed.
