Thanks for your input everyone! I wanted to confirm that increasing the somaxconn also fixed the issue for me.

Kevin


$ cat /proc/sys/net/core/somaxconn
128

by default, which is right about where the problem starts.  After

$ sudo sh -c 'echo 1000 >/proc/sys/net/core/somaxconn'

*and restarting the PG server*, I can do a lot more threads without
a problem.  Evidently, the server's socket's listen queue length
is fixed at creation and adjusting the kernel limit won't immediately
change it.
