Hi,
I am experiencing e problem that havent have before. Are 3 years that all seems to work fine  with syslog-ng 3.05. recently I have find that some of my servers sends syslog messages to syslog server,
Syslog server interface recive it, syslog-ng elaborate it but do not write on file system.

I have configured syslog-ng server to log message in the following manner /opt/logs/$YEAR/$MONTH/$DAY/SERVER/$HOST/messages
What I have done:

-          Listen on eth4 to look for udp syslog messages coming form server A

-          Try to access via ssh to server A

-          I have seen udp packet from A to syslog-server.



Than I have investigate on syslog-ng

-          I have get the pid of syslog-ng and make a strace -p pid -o prova.txt

-          Try to access via ssh to server A (to let server a send udp syslog message to syslog server)

-          Stop strace

-          Look on prova.txt for IP of server A and find It!
But I cannot do more, can someone help me?
