I did earlier tests with the same software on FreeBSD 6.3 and never saw 
ETIMEDOUT -- only on FreeBSD 7.0.

But I did have a different issue with 6.3 (lockups under very heavy 
conditions), although didn't do any specific tuning to try and stop this. 
Instead I made the jump to 7.0 which stopped this problem but introduced 
the ETIMEDOUT one.
