ERR_CONNECT_FAIL

I'm running Squid 1.1.11 on a Solaris 2.5.1 machine with all the latest
patches. My squid talks to another squid on the corporate filewall.
Since there's only one parent and no siblings , I'm not using ICP.
Several times a day users will see the following message on their
browser:

ERR_CANNOT_FETCH
No peers to query and the host is beyond your firewall.

Cache.log has the following:

97/07/25 12:37:43| TCP connection to firewall.whirlpool.com/8080 failed

97/07/25 12:39:03| TCP connection to firewall.whirlpool.com/8080
succeeded

This happens several times a day. Each time the problem lasts for
exactly 20 seconds. I've verified that the parent is up when this is
happening. I also saw it in 1.1.8 and hoped it would be fixed with
1.1.11.

Any ideas or suggestions will be welcome. TIA
