strange squid behavior (1.1.5 on linux 2.0.30)

Hi,

I am new to squid and I installed it recently.
I let squid connect to my provider's squid (my universtiy)
I got something like this in the cfg file :

cache_host wwwcache.rrz.uni-hamburg.de parent 81 3130

anyway I start squid when I boot like this:

/usr/bin/squid -UVD &

ok - in order for squid to get connected to my providers squid I give
it a kill -HUP `pidof squid` & in /etc/ppp/ip-up but then this happens:

97/06/06 05:48:08| reconfigure: SIGHUP received
97/06/06 05:48:08| Waiting 30 seconds for active connections to finish

squid dies ! It doesn't restart.
But the strange thing is when restart squid and do everything all over
for the SECOND time it works, squid doesn't die and restarts:

97/06/06 05:55:24| reconfigure: SIGHUP received
97/06/06 05:55:24| Waiting 30 seconds for active connections to finish

No I would like to know why it doesn't work in the first place - its
pretty ugly to restart squid by hand.
It is only hte first time that kill -HUP `pidof squid` kills squid
without restarting it

thx

bye
