Backup Navigator collecting issues

Hi Community,

i have installed HP Backup Navigator 9.1 in a test environment (CentOS6.6) as a proof of concept for one of my customers.

Noerror during installation. Creatingthe databaseandconnectto theCellManagerwas successful.

But BN collect only Cell- and Deviceinfos. No SessionReports.

From the agent_core.log:

15-06-09 14:52:12 ERROR () SessionReportsManipulation - Cannot fetch full report data: java.lang.NullPointerException
15-06-09 14:52:12 ERROR () SessionReportsManipulation - Error while collecting / inserting session report: java.lang.NullPointerException

and

15-06-09 15:34:04 FATAL (servername) AgentService - Agent failed: java.lang.NullPointerException
15-06-09 15:34:04 INFO (servername) DBconnect - Agent status changing from 0 to 100

Any Ideas?

Thanks in advance!!!
