Hi, 

We have an OPC UA server in the IoT, and we connect to it through UA Expert Client. The connection is OK but after 15-20 minutes running, node-red crashes and the server goes down. Instead of connecting the client, if we just let the server running in node-red, it works properly.

See the error in the attachment.

The backtrace is pointing into nodejs - nasty. I suppose there is no a way to reproduce within commonly available setup, is there?

We recently updated nodejs in its stable series, see master branch of meta-iot2000. Are you running that version already?

How can I check that?

I am using the provided example image.

Yes, I have used the v2.1.3. of the image, downloaded from the forum.

We have already "solved" the problem using the command "node --nocrankshaft /usr/lib/node_modules/node-red/red &" to initialize node-red (instead of node /usr/lib/node_modules/node-red/red &". This executes node-red without the optimize compiler, which is the one that was producing the error.
