Glad you are making progress! I assume you ran "squid -z" after removing slot-size=2048 but please correct me if my assumption is wrong. I suspect the warnings are caused by rock index building code assuming that one database slot is always enough to store cache entry metadata. With a 2KB slot, some metadata (e.g., containing long Vary values) may overflow into the next db slot. The metadata is probably stored correctly, but the index building code does not load its tail, resulting in warnings. I recommend filing a bug report with Squid bugzilla about this, referring to this email message. As a work around, consider increasing your slot size. No supported size will be 100% sufficient until the bug is fixed, but I speculate that 16KB should cover most cases. You may be able to go lower. Unfortunately, I do not know what the store entry metadata size distribution looks like [in your environment] and Squid does not really report that, so I am just guessing, and you would have to experiment.
