Cannot access a disposed object : LogWriter

Sep 4, 2015 at 2:14 PM
Hello,
often i receive this error :
Cannot access a disposed object.
Object name: 'Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter'
I simply defined a static class with a static method where I perform this method call :
ExceptionPolicy.HandleException(e, category);
Where am i wrong ?
Thanks,

Fabio
