Please try an upgrade, there have been a lot of fixes in the 3+ years since that release. Current production/stable release is v4.5. For the FTP issues 3.5.28 would be enough of an upgrade. But ... Since you are also using SSL-Bump you should be tracking the latest Squid releases and upgrading frequently.

Another possibility is one of the ICAP bugs which have been fixed in later v3.5 releases.
