 i also do not have ipv6 compiled into my linux
kernels. When the sendmail binary had ipv6 enabled i
had frequent milter stability problems. sendmail config
had no effect on this. To repeat, when i had ipv6
enabled sendmail binary running the milter is unstable.
when i rebuilt sendmail without ipv6 the milter became
very stable. no changes in sendmail.cf generated by
sendmail.mc ... I tried many ... i repeat many! :-)
configuration tweaks. I do use sendmail's rbl feature
rather liberally .. spamcop, osirusoft, and a few other
favorites ... there may be a link with these and ipv6.
I was able to get sendmail responding quicker to 
connections but the milter was unstable until i rebuilt
sendmail without ipv6.
 will cut and paste watchdog script i am using, this is
derived from other scripts and stuff. basically do a 
ps ax and pipe through grep then through wc looking for
at least three spamass-milter entries. I never saw the
milter hang with three or more spamass-milters present?
 change here, gonna attach instead .. using simple 
web interface for email here and cutting and pasting
the special characters did not go well! :-)
