Hi, I found the problem. In the destructor of helper class the appender was closed. So when GC removed temporary log helper it also killed the appender. I have to find out a better sollution. Small questions. 1.If I use immedeate flush do I MUST to close appender? 2.If I don't use immediate flush do I MUST to close appender? 3.If I use ExclusiveLock do I Must to close appender? 4.If I use MinimalLock do I must to close appender? 5. Is appender closed when log4net destructed?
Thank you for your help very much. For me log4net is a great logging system and very easy to use. With best regards, Boni
