The cache.log entries tell you all you need to know. It means that a client sent a request with a header that was too large for your configured limit. The error message tells you how large the header was and what the configured limit is. Using the timestamp, you can likely correlate this with the access.log entry which will tell you which client was making the request so you can find out what the client was doing that triggered this.
