We know this is pointing to an specific file.

We check that an the file is empty.

We are trying to do a clear installation an this is the only problem we could identify.

7/13/12 06:26:47.182 PM BRT [INFO] [main] [Manager] Introscope Enterprise Manager started with management module warnings.

Maybe this is only a kind of warning but we want to know if somebody else had the some message like this.

If you have passed something similar to this, please, let us know how can we correct it.

Best regard.

The file has a current date and time stamp, but is empty??

Any answers?
