Introduction:
while trying to maps traps from mibtools in Spectrum, the following error is received.

<Landscape_1> Failed: Landscape service is already busy creating trap support for <my_username>@<Landscape_1>".

 
Background:
When a client is connected to the SpectroSERVER, it locks the database, so no other clients can connect and update at the same time.
e.g. mib tools, CLI or Modeling gateway connections will all lock the SpectroSERVER.
Instructions:
Please check that other users who are connected to the SpectroSERVER via clients such as mentioned above, disconnect fully afterwards.
If a user has left a client connected, restarting the SpectroSERVER should kill the connection but sometimes it jsut changes the SpectroSERVER mentioned in the error message.

Previous Error:
<Landscape_1> Failed: Landscape service is already busy creating trap support for <my_username>@<Landscape_1>".

after restarting the SpectroSERVER in <Landscape_1>

Current Error:
<Landscape_2> Failed: Landscape service is already busy creating trap support for <my_username>@<Landscape_2>"

In this situation, it is necessary to kill the MLS also.
