saran sundar created LOG4J2-878:
-----------------------------------
Summary: Failover appender throws "Error flushing stream //L-Computer1/test/logs/primary.log" at the time of retry, but the location is up
Key: LOG4J2-878
URL: https://issues.apache.org/jira/browse/LOG4J2-878
Project: Log4j 2
Issue Type: Bug
Components: Appenders
Affects Versions: 2.0.2
Environment: development and will be moved to production in a weeks time.
Reporter: saran sundar
Priority: Critical
OS: Windows
Software platform: j2ee, spring, webservices, junit, log4j2
I want to make sure that the failover configuration works as expected.
I configured failover appender with two rolling file appenders. Primary rolling file appender configured to a shared folder in different computer. Secondary file appender pointing to my local file system. Once after i ran the junit program and the first debug statement printed, i removed the share location from the other computer in the network for the primary appender. As expected next debug statements ( i left thread.sleep(30000) in between each debug statement in junit program) were redirect to secondary file appender. However at the time of retry by failover appender , it tries to reconnect to the primary location which is up now (enabled the share location in different computer), but received following error..
