[mod-security-users] PCRE limits exceeded

[Art A. S. <art...@gm...>]

I'm running into this on a fresh install of mod_security 2.5.12 with
crs_2.2.1 on CentOS 6. For every page request, I get **two**
occurrences in the error logs of this message: ModSecurity: Rule
execution error - PCRE limits exceeded (-8): (null)

I have been able to eliminate the error by setting: SecPcreMatchLimit 8000

However, this seems like an awfully high setting, given the default of
1500. Is this expected behavior, or should I be concerned?

And when the error occurs, does this indicate that mod-security has
halted rule processing for the request (i.e. dropped protection)?

Thanks.
