There are benefits and drawbacks to each method. In general I favor a lock, open, write, close, unlock pattern because it offers the most protection (multiple servers can use the same log, the log can be rotated out from under the running process, etc); however, if you have a large amount of logging data you may wish to use a log server instead. -- Chas.
