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. Mark
