how much memory is Squid using? Show us the output from:

        squidclient mgr:info

that looks like this:

        Resource usage for squid:
                Process Data Segment Size via sbrk(): 141206 KB
                Maximum Resident Size: 150620 KB
                Page faults with physical i/o: 5
        Memory accounted for:

                memPoolAlloc calls: 337571214
                memPoolFree calls: 334378229
