>Description:
If round-robin load balancing is enabled, pf logs a message indicating which address was chosen for each new state that is created. This produces a prodigious amount of information on a busy server, which can render the server unusable, but the message is logged at priority PF_DEBUG_MISC.
PF_DEBUG_MISC is identified as for "various errors." Selecting a destination address is ordinary operation, not an error.
Therefore I believe the appropriate log level for this message is PF_DEBUG_NOISY.
>How-To-Repeat:
1. Run "pfctl -x misc" on a busy machine that uses round-robin load balancing.
2. Cringe.
>Fix:
Change PF_DEBUG_MISC to PF_DEBUG_NOISY at line 2407 of pf.c in this revision:
/* $FreeBSD: src/sys/contrib/pf/net/pf.c,v 1.34.2.8 2007/11/21 13:52:04 dha

/* $OpenBSD: pf.c,v 1.502.2.1 2006/05/02 22:55:52 brad Exp $ */
