Hi Dave,

Oh! I meant you have two choices, compile with

./configure --without-pthreads --without-solaris-threads

or

./configure --with-libevent

Using them together is indeed also an option.  Perhaps the first one
(without libevent) does not have the errors about resource unavailable
printed.

Resource unavailable ; what is your ulimit -a?
Set open file (file descriptors) to 8*2048 or more, say ulimit -n 100000.

There are no stats for the other threads - but they do print them to the
file!  It is like your logfile is losing information (some syslog version?)

You have an 8 processor but one is doing all the work.
Is your OS unfair in scheduling (raging herd problem)?
Getting the other 7 cores to do some work could help a lot, perhaps the
other two compile modes cause the OS to schedule it differently.

Anyway, with your current --with-libevent compile, you could set
outgoing-range: 16384
num-queries-per-thread: 16384
or even more, and perhaps the thread0 that does all the work gets enough
power to do all of it ...

Best regards,
   Wouter
