[squid-users] squid crashing with error message

I get this message often (see below). Squid will then abruptly exist causing the cache to be dirty. Once squid restarts it works on cleaning the cache. This causes large performance decreases (avg mean time for a response goes from 200 ms to 2000 ms. Does anyone know what might be causing this error?

Thanks,
Steve
