-------------------------------------

Yes, in which case it isn't a Log4j problem.

> Hi Team,
> The problem is when I use file appender with below configuration.
> In each application thread I am calling "initLog4j" followed by other function mentioned
in below class, JVM at server level not application level which is configured to load log4j
specific jar files. The log files are getting created as per my configuration but being a
Admin when I try to open them I am getting messages " document "..........." is under use
by some other application and can't be accessed." I can see one thread is still running although
my application thread is ended.
> As per my understanding if admin can't see the logs even when application is running,
no use of such logging , Could you please confirm is this expected behavior, is their any
alternative for this.....?
