[syslog-ng]syslog-ng keeps erasing my log file - I don't know why

I made a little syslog-ng.conf as follows and tried running syslog-ng. I just checked after a few days and now my /var/log/messages is wiped out. Why did syslog-ng wipe out my /var/log/messages?? Is the fault my syslog-ng.conf below?? options {chain_hostnames(off);}; source src {unix-stream("/dev/log"); pipe("/proc/kmsg"); internal();}; destination dest {file("/var/log/messages");}; log {source(src); destination(dest);}; Chris -- _______________________________________ Dr. Christian Seberino SPAWAR Systems Center San Diego Code 2872 49258 Mills Street, Room 158 San Diego, CA 92152-5385 U.S.A.
