We lost in production some hourly rolled log since we use
org.apache.log4j.rolling.TimeBasedRollingPolicy with gz. This happens for
the appender named "File".
Anybody saw that? Any solution?
It seems to happen only under load. Log4j do not leave any useful trace of
the reason other than: log4j:WARN Failure in post-close rollover action
