[jira] [Closed] (LOG4NET-577) Log4net gives error on UpdateLogFilePath when logfilepath changes dynamically for an appender.

     [ https://issues.apache.org/jira/browse/LOG4NET-577?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dominik Psenner closed LOG4NET-577.
-----------------------------------
    Resolution: Information Provided

I believe that it would be wise to refactor your codebase such that the logging framework is instantiated and configured at startup. Typically I recommend to have one ILog instance for every class by adding a static field or property. Note also that while reconfiguring the framework at runtime is supported, there are edge cases that need to be taken care of.

Please reopen the issue in case you have further questions.
