I have made some suggestions when I answered the same question at
https://answers.launchpad.net/ecap/+question/66951

Please follow those suggestions. Until the culprit is found, you can
post either here or on Launchpad, whichever works best for you.
Launchpad eCAP answers are probably easier for other folks to find in
the future than a squid-dev thread.

Thank you,
