[squid-users] configuring diskd on FreeBSD

Greetings,

trying to set up diskd on FreeBSD 4.3 I got confused enough to ask you
people.

FAQ (http://www.squid-cache.org/Doc/FAQ/FAQ-22.html#ss22.6) mentions message
segments but says nothing about 'msgssz' and instead talks about tweaking
'msgmax'. Meantime FreeBSD (from around end of June) reports this on 'ipcs
-Q':

 msgmax: 16384 (max characters in a message)
 msgmni: 40 (# of message queues)
 msgmnb: 2048 (max characters in a message queue)
 msgtql: 40 (max # of messages in system)
 msgssz: 8 (size of a message segment)
 msgseg: 2048 (# of message segments in system)

>From which follows 'msgmax' in the FAQ is actually 'msgssz' in FreeBSD
and the questions:

1. Is the last conclusion always right (as applied to the FAQ)?
2. Should it be reported to Duane?
3. (unrelated) How come 'msgmax' is greater than 'msgmnb'? As I read e.g. in
   Solaris and IRIX it is the opposite?

Thank you.
