Kamran commented on LOG4NET-178:
--------------------------------

Removing immediateFlush property doesn't effect anything.
What I see is following Last error after which error logging stops

>          Issue Type: Bug
>          Components: Appenders
>    Affects Versions: 1.2.10

>            Reporter: Richard Nijkamp

> Dear sir/madam,
>  We are using Log4Net 1.2.10. We encounter the problem that Log4net doesn't 
> continue logging after an event that triggers an appdomain recycle/restart.
>  In the global.asax we start the logging with:
>  private static readonly ILog log = 
> LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
> Logging works flawless when the application is started for the first time. 
> After sometime it might occur that the appdomain gets recycled due to 
> inactivity of the web application. We use the following code in 
> Application_end():
> log.Info("*** Application end ***");
> log4net.LogManager.Shutdown();
> After this function the application gets restarted and the 
> Application_start() method executes and writes new lines to the log. The 
> problem is that the log4net doesn't write the new lines after the restart. 
> Could you explain why log4net might stop working after an appdomain restart 
> of an asp.net2.0 web application? If I want log4net to work properly again I 
> need to restart IIS manually.
>  Looking forward to your reply.
> Best regards,
> Richard Nijkamp
