Nothing to be solved. When the OS runs out of memory or squid exceeds its available cap bad things happen. What you need to do is figure out how to prevent any such memory overrun. By the look of all those negative counters, I think your Squid is 32-bit limited and may be trying to allocate more memory than it can handle. Try a newer version and see if the larger counters fix your issue. One common mistake is not knowing the cache_mem is the _minimum_ amount of RAM Squid uses (allocated as RAM-cache), with all the indexes and live running stuff on top of that. Or, not having enough RAM on the box (Squid will run with as low as 32MB, but very slowely).
