Subject [jira] [Created] (LOG4NET-496) RollingFileAppender.ActivateOptions throws UnauthorizedAccessException
Date Thu, 10 Dec 2015 15:04:11 GMT
Fabian Pachner created LOG4NET-496:

             Summary: RollingFileAppender.ActivateOptions throws UnauthorizedAccessException
                 Key: LOG4NET-496
                 URL: https://issues.apache.org/jira/browse/LOG4NET-496
             Project: Log4net
          Issue Type: Bug
    Affects Versions: 1.2.14
            Reporter: Fabian Pachner

We upgraded our Azure cloud service project from log4net 1.2.13 to 1.2.13 and received the
following exception when the web roles are starting up:
System.UnauthorizedAccessException: Access to the path 'C__Resources_directory_9b9a1e064b78414281c81f861d0634b0.Role.Web.Frontend.DiagnosticStore_LogFiles_UI_UI_0'
is denied.

   at log4net.Repository.Hierarchy.XmlHierarchyConfigurator.ParseAppender(XmlElement appenderElement)

This affects the w3wp process of the web role. A consequence of this is that file logging
isn't working for that process. We didn't have that exception with log4net 1.2.13 and recognized
there was a change in 1.2.14 in RollingFileAppender.ActivateOptions: A mutex is created there
and that seems to lead to the mentioned exception.

Can you tell us whether it is likely that this issue was already fixed with 1.2.15? And if
so, when will this version be available via Nuget package? Thank you!
