Hello Igniters! I currently see a lot of issues with Ignite deployments where problems are caused with improper JVM or OS setup, e.g. OS user has too small open files limit, Ignite's JVM has very small max direct memory size resulting to OOME in some cases.
I suggest to add some validation to Ignite so we output warning to log on startup or at any other moment problem is spotted. Here is the ticket - https://issues.apache.org/jira/browse/IGNITE-4374. Please comment. Alex Scherbakov, I know you have many points to add - please feel free to proceed. --Yakov
