Hi all!
Rahul - there is nothing relevant in the attached file, you've probably executed LogTool on "working environment", so there is nothing interesting in it.
I think that you had to mention the Error we've detected in an already "crushed" environment, just as I was suggesting you to do.
Yes, nothing interesting in the attached logs.
Alfredo - this Error was logged almost on each OC node at the same time when the problems had started.

I'd suggest to check rabbitmq and mariadb logs.
AFAIK, there is not a configuration that may limit the number of networks or project, but it may be hitting some resources scarcity that affect the running services. What's the memory sizing and usage of the controllers?
You can find more Error Blocks in the attached file.
Thanks!
