Cache update failed

Hello,

I'm work with Alfresco CE 4.2.d running on Centos 6.4 x64.

Today, after restart the Alfresco service log file show the next message continuously:

I've search on internet and not found any information that help me to solve this issue.

I try, full reindex, delete tomcat/work and temp directory, but the error continue.
