[Mod-security-developers] Retrieving collection error

[Netstar S.r.l. <in...@ne...>]

I installed and configured mod_security (v. 2.6.4 with Core Rules 2.2.3) on 
a ubuntu platform. Qhen I Activate the configuration, log files are 
saturated with messages like these:

[error] [client xxx] ModSecurity: collection_retrieve_ex: Retrieving 
collection (name "global", filename "/xxx/global") [hostname "xxx"] [uri 
"/xxx/"] [unique_id "T19DmX8AAQEAAA6qUHYAAAAC"]
[error] [client xxx] ModSecurity: collection_retrieve_ex: Retrieving 
collection (name "ip", filename "/xxx/ip") [hostname "xxx"] [uri "/xxx/"] 
[unique_id "T19DmX8AAQEAAA6qUHYAAAAC"]
[error] [client xxx] ModSecurity: collection_retrieve_ex: Retrieving 
collection (name "global", filename "/xxx/global") [hostname "xxx"] [uri 
"/xxx"] [unique_id "T19Gpn8AAQEAAA-ZHmUAAAAH"]
[error] [client xxx] ModSecurity: collection_retrieve_ex: Retrieving 
collection (name "ip", filename "/xxx/ip") [hostname "xxx"] [uri "/xxx"] 
[unique_id "T19Gpn8AAQEAAA-ZHmUAAAAH"]

The configuration file is set with these values​​:

SecTmpDir / xxx
SecDataDir / xxx

where xxx is an operating system folder with permissions set to write for 
apache.

I checked several times but I can not find the problem.

Someone could help me find a solution?

Thank you.
