Matt Sicker commented on LOG4J2-174:
------------------------------------

I'd also suggest a database appender like the new Cassandra appender, but I 
can't imagine that's much faster than all the file locking needed to implement 
that prudent mode feature.

> Multiple instances of same application server cause 2 problems - want to know 
> if they are solved in log4j 2

> When we start multiple instances of application server using log4j 1.2 and 
> all instances read same configuration file, two problems are noticed. 
> 1. At rollover time first app server doing rollover will do its job properly 
> but when subsequent ones will do rollover again and we lose logs. May be 
> log4j should check that if rolled over file is already present, it should 
> skip rollover.
> 2. After rollover only one instance is logging and others stop logging. The 
> problem is that the active file was rolled over and new file is created. Only 
> one server has pointer to it.
