Acronis Agent Linux XEN

I have a problem starting acronis agent on Debian running throug Xen Server.

Install went correct.
But when starting:

ip73:~# /etc/init.d/acronis_agent start
Starting Acronis Agent:
ip73:~# /etc/init.d/acronis_agent status
Acronis Agent is stopped
ip73:~#

Version:
Linux 2.6.18.8.xs5.0.0.10.439 #1 SMP Wed Aug 6 23:55:12 UTC 2008 i686 GNU/Linux

Does somebody know where to find error log our issue to start ?
