Dominik Psenner commented on LOG4NET-496:
-----------------------------------------
I thought a little bit about this and what I am wondering about is why you are
using a rolling file appender in a cloud scenario. If I do not know on which
machine my code executes, a file appender is the wrong appender for this
usecase, isn't it?
> 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 1.2.14 and
> received the following exception when the web roles are starting up:
> {code}
> System.UnauthorizedAccessException: Access to the path
> 'C__Resources_directory_9b9a1e064b78414281c81f861d0634b0.Role.Web.Frontend.DiagnosticStore_LogFiles_UI_UI_0'
> is denied.

> j:\Source\Commons\Logging\AzureFileLogAppender.cs:line 95
> at
> log4net.Repository.Hierarchy.XmlHierarchyConfigurator.ParseAppender(XmlElement
> appenderElement)
> {code}
> 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!
