Pentaho BI Server 5 working in CentOS 6.0 but not in CentOS 6.5?

Hi comm,
I've got issues when trying to run Pentaho BI Server 5.0/5.1 in CentOS 6.5. I did the same "installation" and config for Pentaho CE in both Centos 6.0 and 6.5. Stopped iptables just to avoid any port restrictions. Installed JRE 7 update 67 and configured /etc/profile to include Java paths. On Centos 6.0 it works just fine, but I can't get it working on Centos 6.5. I even tried with OpenJDK and get same results, Centos 6.0 working, Centos 6.5 not.

This is what .../tomcat/logs/catalina.out looks like after starting Biserver in Centos 6.5, and trying to access it through the web browser:

.../tomcat/logs/pentaho.log shows that apparentely there's a problem with jackrabbit. It says that the repository home /opt/pentaho/biserver50/pentaho-solutions/system/jackrabbit/repository appears to be in use since the file named .lock is locked by another process, but I couldn't find any .lock file. Where should this file be?

Any ideas?

Thanks in advance.
