I had problem that all my node cunnections was Stucked during hole night, a get 0 ingress.
Limit was 40 connections all of them was stacked, and there was no loadings and untill restart all 40 connections was bloked. Each connection should have resonoble time and then be kiled, then there will no stucking. I know that tere is no limit today, but if 40 connections was stucket, then could be also 1000 stucked same way. Each connection is processor time and memory.
