--------------------------------------
[~ralph.go...@dslextreme.com]: thanks for the offer. I will open a new JIRA
ticket and link it to this one.
[~jvz]: good suggestions. In our case we actually do our log aggregation in
kafka and/or splunk already. The purpose of the prudent option in our case was
simply for legacy reasons for supporting our existing setup for logging within
storm, which has upgraded from logback to log4j 2. For the time being we will
be changing the log files that each process emits to have a UUID in the
filename.

> URL: https://issues.apache.org/jira/browse/LOG4J2-174
> Project: Log4j 2
> Issue Type: Question
> Components: Appenders
> Environment: Unix based OS and Java based application servers
> Reporter: Jas Gill
>
> 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.
