Tried to increase UDP udp_max_buf to 524288 (from 262144) - doesn't
STATS reports 0 lost messages... ;(

Plus 1.6.3 hangs for me after 200-300 messages (3-5 minutes)... 1.6.1
doesn't hang but losing messages :(

if the packet arrives to the log host but syslog-ng does not receive it
(e.g. your STATS line shows 0 dropped messages), it is possible that the
UDP receive buffer is too small.

try increasing the UDP receive buffer, it should be possible with some
OS dependant tools (ndd comes to mind on Solaris)
