[logback-user] Does logback really lose events during reconfiguration?

I have read here < http://logging.apache.org/log4j/2.x/manual/index.html > that "Both Log4j 1.x and Logback will lose events while reconfiguring." Is it really true? Does it mean that some log entries, that happen during reconfiguration, may not be logged at all to the log file? -- Wojciech Kopras
