log4net duplicate entries - log4net

I'm new to log4net and been reading and reading and come to no conclusion of what my problem is.
Here is the configuration:
<root>

When I go to a .NET page and in Page_Load this statement executes:
log.Error("hi")
i get this error as an entry in my database table. But if i go to this page again rather quickly i get a total of 3 entries? It seemes that if i wait ~10sec before reloading the page i get only one more entry. I have set the buffersize to 1. Anyone who had the same problem? The most part of the community tends to say that if there is a problem then it's most likely in your configuration but to me me my configuration looks fine.
Greatly appreciate any who can shed som lights over this!

Log4Net is probably working just fine. It is logging what is happening.
You need to figure out why Page_Load is executing when you don't expect it.

Asking about log4net just write to appender when i stopped site

Currently, I already config my project, but I got the issue
I can't query any message when the site is running.
When I stop the site, I can query it on database again and I see them.
Why do I just see message when I stop the site?
This is my code.

I dont know what is correct concept on the log4net.

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

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)

</connectionStrings>
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.

Log4Net AdoNetAppender - Formatting log date to get seconds included

My issue is that my Database logging does not display seconds (default format seems to be "yyyy-MM-dd hh:mm:00".
Is there any way to change this and get something with seconds at least (miliseconds would be a plus)?
Here is my appender config:
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="1" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

<parameter>
<parameterName value="#exception" />
<dbType value="String" />
<size value="2000" />
<layout type="log4net.Layout.ExceptionLayout" />
</parameter>
</appender>
Thank you for your help!
EDIT: Just as suggested by leppie, I checked my Date type in database, which was smalldatetime. I changed it to datetime and now my logs are as expected (with seconds & milliseconds)
Change #log_date parameter like this:
<parameter>
<parameterName value="#log_date"/>
<dbType value="DateTime"/>
<layout type="log4net.Layout.PatternLayout"
value="%date{yyyy'-'MM'-'dd HH':'mm':'ss'.'fff}"/>
</parameter>

<appender-ref ref="SQL_Hibernate" />
</logger>
They work perfectly but all logging is saving DEBUG messages, even having configured not to do so. What am I missing here?
It should work when you configure it like this:
<logger name="NHibernate" additivity="false" >
<level value="ERROR" />
...
Note: that I use value instead of name in the level node (do this for the root "level" element as well). Turning on internal debugging would reveal this kind of problem.
Just a thought, check your log appenders to see if they have something like the following configured:
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ALL"/>
</filter>
DEBUG is a lower level than INFO, so I suspect that the DEBUG messages are being logged because the root logger is set to log at the INFO level.
See this post if you want to get the INFO messages but not the DEBUG messages.
