Thanks for your answer!

Is there any way to estimate how much shared memory I should make available
to Squid?

My Sun machine has 2 gigs of mem, and 36 gig of cache space on disk. There
are a 1000 users who use the proxy.
The actual shm settings in /etc/system are the following:

set shmsys:shminfo_shmmax=268435456
set shmsys:shminfo_shmmin=100
set shmsys:shminfo_shmmni=200
set shmsys:shminfo_shmseg=100

set semsys:seminfo_semmni=250
set semsys:seminfo_semmns=500
set semsys:seminfo_semmsl=250
set semsys:seminfo_semmnu=500
set semsys:seminfo_semume=50

set msgsys:msginfo_msgmax=4096
set msgsys:msginfo_msgmnb=16384
set msgsys:msginfo_msgmni=100
set msgsys:msginfo_msgtql=1024
