Default is 128 for queue of TCP established socket, but not accepted. It
is called backlog (see man listen). This values is possible change by
ndd command. However problem is, that unix domain socket has different
backlog limit. This limit is 32 waiting request for accept and this
value is not possible setup. However, kernel patch 118855-15 increase
this value up to 128 - see bugid 4352289. New version of
solaris/opensolaris has bigger value - 4096.
Please, install latest solaris 10 patches on this machine and check if
it helps.
