Hi,
After updrading Node Red to 0.19.5 opening editor app (at port 1880) makes high memory and CPU consumption and ultimately crashes the process, but with no error message. When I start it from console it just hangs and doesn't react to Ctrl+C. I roughly isolated problem - loading one of complex flows makes the process crash when opening Editor.
When I don't open Editor it works with UI Dashboard as well. Also when I start Editor with that flow disabled, and then enable and deploy the flow everything works. Only refreshing the page in the browser hangs the process.
Unfortunately I don't remember what Node Red version I've been using before update. My current configuration is:
Node-RED version: v0.19.5
Node.js version: v8.9.4
Linux 3.2.40 arm LE (Synology DSM)
