[Owasp-modsecurity-core-rule-set] What does this mean

With the installation of the latest rulesit, I'm 
now getting the following alerts:

Warning - Sticky SessionID Data Changed - 
User-Agent Mismatch.    Access denied with code 
403 (phase 2). Match of "streq %{SESSION.UA}" 
against "TX:ua_hash" required.

Hope I'm not being too stupid here, but what does 
that mean?  Am I blocking legitimate traffic?

Better still, is there a place (documents, etc.) 
that describes various alerts?
