Title: RE: What do I need to do to get rid of this error? Please help

I'm not sure if this problem is related to the change (setting the lockingtype to minimalLock) that I just made. I am now seeing too many duplicate log statements in my log file. This is the first time I'm seeing this. Here is the sample of my logs

2005-11-07 08:57:17,925 INFO : busTag.clsRetrieveTag.Retrieve() - Leaving

2005-11-07 08:57:18,832 INFO : UILayer.modUICommon.ProcessAction() - Leaving

2005-11-07 08:57:19,613 INFO : UILayer.clsUIFlow.ProcessRequest() - Leaving

Does anybody know how to solve this? Nicko, I did read this article (http://logging.apache.org/log4net/release/manual/introduction.html#HC-7189308) but I don't know what to do next. Why am I seeing this behavior only now?

I feel like I'm in an infinite loop here. One issue is solved, the next one pops up and the next one and the next.....

Appreciate your help.

I figured it out. Here it is.

log4net.Appender.RollingFileAppender.LockingModelBase m_lockingType=null;

m_lockingType = new log4net.Appender.RollingFileAppender.MinimalLock();

oRollingFileAppender.LockingModel = m_lockingType;

I have tried

log4net.Appender.RollingFileAppender.LockingModelBase m_LockingType = log4net.Appender.RollingFileAppender.MinimalLock;

oRollingFileAppender.LockingModel = m_LockingType;

log4net.Appender.RollingFileAppender.LockingModelBase m_LockingType = log4net.Appender.RollingFileAppender+MinimalLock;

oRollingFileAppender.LockingModel = m_LockingType;

Both of them don't work. Please help me!

How do I write this line in my code? I don't have a config file.

<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />

This line gives me errors.

log4net.Appender.RollingFileAppender.MinimalLock;

By default the log4net FileAppender takes an exclusive write lock on the
log file. If you have multiple processes that are logging to the same
file then you need to use a different locking model. For example the
MinimalLock model:

This locking model takes a write lock on the file as each logging event
written and then releases it immediately.

An example configuration is:
