I'm quite sure ETIMEDOUT is a result of hitting the setsockopt
SO_RCVTIMEO value when doing a read.
I had been thinking along those lines too. But immediately before calling
read, select said

A while ago our systems were upgraded from 4.2 to 4.3-RC, and at
this time we started seeing problems that I am having a difficult
time tracking down.
We have a server process which is connected to by many other
machines, each of them streams data in via tcp/ip. These connections
are pretty much

I have been running truss on the process. The relevant part is

I've seen this behavior in the past. My impression is that it is load related.
If you do a grep on ETIMEDOUT in /usr/src/sys/netinet, you will see where
the tcp stack may return this message. There may be some sysctl params relating
to timers that you can muck with.

ETIMEDOUT may be returned from read(2) or is this a potential bug

But then we have another server, with a similar number of clients and
data through put,
While this does sound very plausable,...
The server does not do any writes, data only travels from the clients
to the server.
The clients and the server are connected to the same switch.
The other server which is similar is on the same network and
is connected to by the same machines as
