Re: Ignite node heap gradually increasing and not getting stabilized

Hello! How many tables do you have? I don't see why you there are so many. I'm not sure who holds all those CipherSuite's. Can you check? If you have a ton of thin client connections with SSL which are doing MERGE on many tables, I guess this may be OKish though. Regards, -- Ilya Kasnacheev
