log4net stop working logging the first user after new release - log4net

My problem is that in development and test environment the code works fine, but when released to production it doesn't work as well.
After the release it will log the first users request which is about 9 different log entries when in INFO level. After the initial 9 nothing more gets logged until the server is restarted. I have now just this bare code in production and it still shows the same behavior.
Any suggestions of what could be causing this?

{
try
{
log = LogManager.GetLogger(typeof(Log));
log4net.Config.XmlConfigurator.Configure();
log.Info(message);
}
catch
{
}
}
}

Why do you first get the logger and then configure the log4net? Usually it is the other way around. E.g.
// Configure log4net
var info = new FileInfo("myapp.log4net");
log4net.Config.XmlConfigurator.Configure(info);
// get the logger
var logger = LogManager.GetLogger(this.GetType());

log4net oracle doesn't work

I made a log4net project with WinForm about keeping logs in the database. I contacted SQL Server and wrote logs here. But when I try to contact to Oracle and save log in Oracle database, it didn't work. Why? I am sure the connection string is correct, but it does not work. Is there something wrong with the connection string or is there something else I need to implement for Oracle?
Here is my Log4net.config

Set another appender in log4net if the first appender fails to log the message

I have added an appender to log in SQL Server using log4net, but I want to add the log messages in application event log if there is an error while connecting to database.
Is there a way to achieve this?

log4net write file is ok but cant insert to database

This is my configuration file contains log4net attributes, if I use "RollingLogFileAppender" appender it writes file correctly but I am using
"AdoNetAppender" and expect to see same string in message column of inserted row. But somehow this not work..
(table defination and query configurations are from apache documentation so it cant be wrong I though connection string is my problem, But application already have connection with the same db I also shared the connection string is being used by adonet)

And .cs file:
private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
if (log.IsErrorEnabled)
{
log.Error("Error ocurred here");
}
if (log.IsDebugEnabled)
{
log.Debug("Debug message");
}
Your buffersize is 100, which means that messages will be written after 100 messages. Change it to 1, it will flush the messages directly to the sql database:
<bufferSize value="1" />
If that does not work, enable log4net interal debugging to see if you have connection problems. Also check if you have the latest version of log4net.

Writing to two locations not working

I feel this should be possible but I can only get log4net to go to one appender at a time.

</root>
<Logger>
<level value="DEBUG" />
<appender-ref ref="RollingLogFileAppender" />
</Logger>
</log4net>
I want the ERROR level messages to go to the database and DEBUG level messages to go to the text file but all the messaging are just going to file.
What am I missing?
Thanks!
You need to configure the root logger as follows:
<root>
<level value="DEBUG" />
<appender-ref ref="AdoNetAppender" />
<appender-ref ref="RollingLogFileAppender" />
</root>
then you add a filter to the database appender:
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<levelMax value="FATAL" />
</filter>
<filter type="log4net.Filter.DenyAllFilter" />
Update:
The problem with your configuration is that you assign the db appender to an unnamed logger and thus your appender in all likelihood never gets called. In log4net you can assign appenders to loggers, but not to levels.

Log4Net Appender Not Loading

Log4Net isn't able to load the appender for the DB2 connection and I cannot see why. It writes the logs to the file system fine, however, the DB2 logging isn't occurring. The version of Log4Net is v1.2.10.0.

At the risk of pointing out the obvious, the config file you posted does not actually use AdoNetAppender. Would this be a matter of replacing RollingFile with AdoNetAppender in the second last line?
If not, can you post the rest of the config file.
