False alert: process instances (Oracle tnslsnr listener)

Hi,

With the processes probe you can monitor the number of instances that the probe should find.
We monitor the tnslsnr listener from oracle DB that there is only 1 instance (It seems in the past there was a bug in oracle, when 2 processes with same name are active the users are no longer able to log in).
Nimbus is often reporting that he find 2 instances instead of 1, this for 10 seconds and then closes the alert again. Does anyone have the same problem?
The simple solution is to send the alert after 10 seconds, but the false alert is bad for our statistics we deliver to the upper management.
How can I filter the messages for the first 10 seconds?

Best regards,
steven
