sonewconn: pcb 0xfffffe00c7223498: Listen queue overflow
Hello,
I updated our main server to 9.2-STABLE today and afterwards I noticed a
bunch of these messages, does anyone know what they mean? I was unable
to find anything on this error message. Things appear to be working OK
so far.
Sep 30 22:08:56 illidan kernel: sonewconn: pcb 0xfffffe00c7223498:
Listen queue overflow: 193 already in queue awaiting acceptance
Sep 30 22:12:27 illidan kernel: sonewconn: pcb 0xfffffe00c7223498:
Listen queue overflow: 193 already in queue awaiting acceptance
Thanks!

samba4 ldap high load and port queue overflow
...Cs have 3 CPU and 3GB RAM. Some servers with services
like apache, exim, dovecot, etc use samba4 ldap (port 389) for user
authentication. Some times ago after adding some services to use ldap I
found, that samba4 cannot serve all ldap requests. Every 10-30 minutes I
see in DCs logs:
dc1 kernel: sonewconn: pcb 0xfffff800753d6ab8: Listen queue overflow: 16
already in queue awaiting acceptance (28 occurrences)
After that I have used tcpdump for recording ldap-traffic and have seen
that after TCP handshaking, server some times suddenly send TCP-RST to
close connection. I have enlarged DCs resources...

Samba46 Listen queue overflow in FreeBSD 11.1
...46-4.6.8
This server is hosting all data in ZFS pools. This server gives out NFS shares
to other servers and holds the end user shares for Linux and Windows.
When the server is up for about 24 hours we start to see these errors in
/var/log/messages. The occurrence number could be more.
kernel: sonewconn: pcb 0xfffff8018a4ba3c0: Listen queue overflow: 8 already in
queue awaiting acceptance (1 occurrences)
The load increases on the server by ~3 and more CPU is also used right after the
first error. After more time has past we slowly see more queue errors, maybe a
few every hour. After a few days th...
