Running selecttest, I have built 9.4.2-P2 with FD_SETSIZE=4096 and deployed
it on our internal root servers running Solaris 9 SPARC. After a week of
monitoring fd usage (once a minute via cron) I found that it remained
way below the configured limit, and we haven't logged any "too many open
file descriptor" errors.

There were other errors I haven't seen before, though, like

dispatch: info: dispatch 1ecfb10: shutting down due to TCP receive error: 213.198.65.226#53: connection reset

general: error: malformed transaction: hosts/internal.com.jnl last serial 964384 != transaction first serial 964383
