[syslog-ng] so_rcvbuf default value of 0

Greetings, Just looking for confirmation about the so_rcvbuf parameter for the udp() source driver. The default is 0. Does that mean that syslog-ng uses the default value from the kernel? ie. cat /proc/sys/net/core/rmem_default 124928 If that is true, then perhaps the syslog-ng admin docs could mention that. I've scanned "man 7 socket" and don't seen anything that suggests that a value of 0 for so_rcvbuf means that the socket will inherit the value. Thanks for the help! -m
