Hard to tell how it is related without seeing what you are logging, but
since that is your best guess, might as well follow up in that direction.
Can you quantify "a lot of logging"?  Are you attempting to log a large
section of the file that is being uploaded?  Or some other large individual
message during the process?  That's where I'd look since it seems to be
appender indepenent.

The file is being uploaded to our servers via web services. I don't see how
it can be related (it's not a new feature), but that is the pattern we're
seeing -- logging stops for some people after they've uploaded. One thing to
note: There is a lot of logging done during the upload process.


One other thing - I remembered last night that I've seen this in one other
case. I put some logging statements in this click event in a user control
once, and it wouldn't output the statements. I ended up putting in
messageboxes to get the information I was looking for.


And the other programmer who has seen this problem said the log messages
don't show up in the Output window in Visual Studio either.


Here is our configuration file. I didn't add the logging to our application,
another programmer did, who is long gone. So I don't know a whole lot about
log4net, except how it's set up in our app (it starts first thing), where
the logs go, and how to write to the log. That, and it's worked great right
up to this moment.

No answers, but some questions: Is the file being uploaded to the same
directory as the log?  Dose the size of the file being uploaded matter?
Which appenders are you using?

Subject: Log4Net stopping

We are using log4net to do logging in a .Net 2.0 application. We have used
it successfully for about 6 months. Then today, we discovered that sometimes
it just stops working. It still goes through the statements to write to the
log, but it doesn't actually write anything anywhere. The users have to
close our application and re-open it to start the logging off again. 


The action that happens right before it stops is uploading a file via web
services. The file succeeds, and shortly thereafter it stops logging. I
don't know if that's coincidence or what. We are not seeing this on all the
customers, just some, and for those, some are intermittent and some are
always happening.


We are running the most current version (1.2.10).


Any help would be greatly appreciated.
