14625	Docs on logging should emphasize that file logging is not multiprocess save	Piotr Czachur	nobody	"python logging facility is not multiprocess save:


""Although logging is thread-safe, and logging to a single file from multiple threads in a single process is supported, logging to a single file from multiple processes is not supported [...]"" (http://docs.python.org/library/logging.html#logging-to-a-single-file-from-multiple-processes)


""Not supported"" means your logs from multiple process can mix in chunks due to buffering issues (I tested it for long messages ~5k - their chunks just got mixed)

Django popular deployment is mod_wsgi/multiprocess so it can be the issue.
