Aumentei a fila com o comando: kern.ipc.soacceptqueue=4096 notei que houve uma melhora mas ainda continua alguém já pegou esse problema e resolveu?
Current listen queue sizes (qlen/incqlen/maxqlen)

Jun 28 10:55:51 kernel sonewconn: pcb 0xfffff8013eb5aa50: Listen queue overflow: 8 already in queue awaiting acceptance (112 occurrences)
ao usar o comando netstat -Aan | grep fffff8013eb5aa50 o resultado

fffff8013eb5aa50 stream 0 0 fffff8005c5b4ce8 0 0 0 /var/run/samba4/winbindd/pipe

algumas vezes alguns usuários reclamam de paginas solicitando autenticação, vocês recomenda aumentar ainda mais esse numero de autenticação?
o numero Authentication TTL esta em 30 minutos será que é pouco para esse tamanho de rede?
