That is normal behavior for nearly all unix based applications. Since 
files are internally represented as file descriptors which are typically 
opened upon starting the application (here: the cod server) and closed 
while shutting down the application, there is no way for the server to 
know if the file has been moved away. If it has been removed and 
retouched, the inode number has changed, and thus the file descriptor 
has become stale. Apache has the nasty habit of completely breaking down 
when this occurs, the CoD server only stops logging.

And since the CoD server probably doesn't support SIGHUP for refreshing 
all file handles, you need to shut down the server before rotating the 
log file and start it afterwards.

Again, this is not specific to the CoD server, it is normal behavior for 
any application, including syslogd.
