Yes I' using RoutingAppender, here is my config:
{code}
<Route>
<RollingFile
name="Rolling-${ctx:sessionID}"
fileName="./logs/${ctx:sessionID}.log"
filePattern="">
<PatternLayout>
<pattern>%d: %6p : [%t]
: [%c{1}] : %m%n</pattern>
</PatternLayout>
<SizeBasedTriggeringPolicy />
</RollingFile>
</Route>
{code}
what I m doing is that I m creating logs base on ThreadContext. My app create a
Thread for each client (session)
log4j2 then create files base on each client session id. so if I have 1000
clients at the time I will have 1000 files or more generated for each session.
Those files are now open and I m logging into it base on the Thread. The
problem comes when the session expired and the file become inactive and stays
open
the more session I create the more files are generated up to a stage where the
OS complaint that too many files are open and the App crash.

> Issue Type: Bug
> Components: Appenders

> Hi There,
> in log4j2 when the App start logging it create and open a file to log into
> and that file stay open as long as the App is running.
> in my case log4j2 create and open too many files base on ThreadContext and
> the OS (linux) will complaint that too many files are open and my App will
> crash and stop responding.
> My question is:
> 1 - how do you close those files with log4j2 if they are inactive for a
> period of time.
> 2 - How do you have access to the log4j2 handle that open those files.
> 3 - How do you tell log4j2 to open a file just for a period of time.
> Thanks
> Eric
