Massimo Del Zotto commented on LOG4NET-602: ------------------------------------------- I would need to allocate some hours to figure out the exact timings. I do not have this possibility. I'd also need to review program flow and windows services lifetime. So far my gut feeling is a chunk of messages is missing but I cannot tell if the missing messages are close enough to the reboot - let me reiterate - I do not have time to review the logs in detail. That said, lack of proof is not proof the problem does not exist. So I don't quite support either proposal, it is necessary to acquire more information. However, I would suggest to downturn priority a bit. I feel classificating this as _blocker_ is extreme. > Log4Net missing messages > ------------------------ > > Key: LOG4NET-602 > URL: https://issues.apache.org/jira/browse/LOG4NET-602 > Project: Log4net > Issue Type: Bug > Components: Appenders > Affects Versions: 2.0.8 > Reporter: Juan Gonzalez > Priority: Blocker > Attachments: log4net.config, log4net.zip > > > I am using log4net 2.0.8 from a C# service. This service has a method that > writes out a status message of application domains that it has loaded on a > timer (normally every three minutes, but set to 30 seconds for testing). What > I have found is that some of our status messages are missing. It appeared to > me from the message, that the code is working, but no message is being > generated. > So, I added a Debug.WriteLine before every Log.Fatal (set to Fatal for > testing) and ran the code. > As you can see from the attached log4net.txt, the code logged successfully > and then failed. > The output should have the following messages. > tmrLogData_Elapsed > LogData, Enter > LogData, appDomainUtilsLoggingList.Count > LogData, 1 > LogData, 2 > LogData, 3 > LogData, 4 > LogData, sb.Count > LogData - start, logDataCounter > LogData, 5 > LogData, Exit > You see the run that failed on lines 302786 - 302810. It has the > Debug.WriteLine calls, but only some of the Log.Fatal calls logged anything. > We are very concerned that log4net may be missing other critical messages. > Please feel free to reach out to me if you need further information. > > > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
