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

[syslog-ng@lists.balabit.hu]

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);};
