---------------------------------------
Summary: Log files are under lock, not able to view them until JVM
stop.
Key: LOG4J2-1231
URL: https://issues.apache.org/jira/browse/LOG4J2-1231
Project: Log4j 2
Issue Type: Question
Components: Appenders
Affects Versions: 2.5
Environment: window, jre 1.7, IBM Integration Bus
Reporter: Yogesh Bhardwaj
Priority: Blocker
Fix For: 2.5.1
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.....?
