You are probably having a very low somaxconn parameter ( default centos has it
at 128 , if I remember correctly). You can check the value under

Aha! Excellent, it does seem it's at the default, and that particular
sysctl item had slipped my notice:
[ellis@pool100 ~]$ cat /proc/sys/net/core/somaxconn
128
Can you also check the value of ulimit -n? It could be low.
I did look for and alter this already, but it is set fairly high from
what I can tell:
[ellis@pool100 ~]$ ulimit -n
16384
I altered both of these in /etc/sysctl.conf and have forced them to be
re-read with `sysctl -p` on all nodes. I will report back if this fixes
the issues tomorrow.
Thanks again to all!
