Minimun number of processes needed for a user to START neo4j

hello all,

I am running neo4j community 5.9 in a RH8 machine. What is the minimun number of proccesses I need to start the neo4j?

I am trying to fix the error:
Exception in thread "main" java.lang.OutOfMemoryError: unable to create native thread: possibly out of memory or process/resource limits reached

I noticed that my max number of processes is 20.

Thank you in advance.

Regards,

Regards,
Pablo G.
