Well, "optimal" depends on your goals.  Looks like you've got a server
log file you rm'ed from the file system, but the server is still
logging to it. You need to convince the server to close the log file,
which will cause it to be removed from the disk. If worst comes to
worst, doing a shutdown and reboot will solve the problem.
