I am getting some errors when i try to set up my client machine and try to send the messages to a remote central server.

This is the error that I get,
syslog-ng service starting.
Plugin module not found in 'module-path'; module-path='/opt/soe/local/syslog-ng-3.3.7/lib/syslog-ng', module='afsocket'
Plugin module not found in 'module-path'; module-path='/opt/soe/local/syslog-ng-3.3.7/lib/syslog-ng', module='afsocket'
