I didn't happen "always" but it did happen occasionally. It appears to
be a strange interaction with persistent connections. Squid is receiving
ECONNRESET's on some persistent connections. e.g.:

21:25:46.580408 surf.16444 > www.onsale.com.http: . ack 12674 win 61440
21:27:33.401131 surf.16444 > www.onsale.com.http: P 150:299(149) ack 12674 win 61440
21:27:33.465228 www.onsale.com.http > surf.16444: R 24326162:24326162(0) win 0

Anyway, Squid has now been fixed to handle this case more gracefully and
the new version is running on our caches. Please let us know if you
notice further problems.
