Hi, I have some difficulties with zimbra server statistics on SLES 10 SP2.
When I try to see server statistics or server status I get the following error:

"Server error encountered Message: system failure: Unable to read logger stats Error code: service.FAILURE Method: GetLoggerStatsRequest Details:soap:Receiver "

Note that SLES 10 is using syslog-ng and in the end of the syslog-ng.conf file I have the following lines added by zimbra:

source zimbra_src { unix-stream("/dev/log" keep-alive(yes) max-connections(20)); }; # zimbra
filter zimbra_local0 { facility(local0); }; # zimbra
filter zimbra_local1 { facility(local1); }; # zimbra
filter zimbra_auth { facility(auth); }; # zimbra
filter zimbra_mail { facility(mail); }; # zimbra
destination zimbra_mail { file("/var/log/zimbra.log" owner("zimbra")); }; # zimbra
destination zimbra_local1 { file("/var/log/zimbra-stats.log" owner("zimbra")); }; # zimbra
destination zimbra_local0 { file("/var/log/zimbra.log" owner("zimbra")); }; # zimbra
destination zimbra_auth { file("/var/log/zimbra.log" owner("zimbra")); }; # zimbra
log { source(zimbra_src); filter(zimbra_mail); destination(zimbra_mail); }; # zimbra
log { source(zimbra_src); filter(zimbra_local0); destination(zimbra_local0); }; # zimbra
log { source(zimbra_src); filter(zimbra_local1); destination(zimbra_local1); }; # zimbra
log { source(zimbra_src); filter(zimbra_auth); destination(zimbra_auth); }; # zimbra


My zimbra version is:
Release 6.0.5_GA_2213.SuSEES10_20100202214859 SuSEES10 FOSS edition.


Can someone help me with this problem?
Thank you in advance.
