log4net is thread safe as it says in the FAQ.=20

How log4net implements this with regards to individual appenders is not
really important. The docs for the RollingFileAppender are correct, the
members of the type are not thread safe, but this is not relevant unless
you want to programmatically access the appender directly from you code.
During logging the appender's base class (AppenderSkeleton) ensures
serialisation of appending of logging events.

You do not need to add your own locking code around calls like:

log.Info("message");

or

LogManager.GetLogger("foo");
