Hi, you might have to increase your UDP receive buffer (so_recvbuf() option in 
syslog-ng) and the net.core.rmem_max option on your host, see

http://www.balabit.com/sites/default/files/documents/syslog-ng-ose-v3.2-guid...

Others have reported similar problems recently with the default UDP settings of 
RHEL, you might have run into the same issue.

Robert
