At our vSphere 5.1 environment, the SQL Express database has filled up, which led to crash the vCenter service.
The database has been flooded with entries in the tables VPX_EVENT and VPX_EVENT_ARG.

Over a sql query, we found that in 5 minute intervals login and logout sessions are created in both tables.

In the vSphere Web Client it could be analyzed in more detail with the logging events.

An un- and reinstalling of the vsc plugin at least brought the improve, that is no longer a one second frequency interval of the logging, but every five minutes.
After searching the internet, we have the log files of the vsc plugin in windows closer viewed -> " C:\Program Files\NetApp\Virtual Storage Console\ log".
The main reason for the filling of the tables in the vCenter database is the log file named "requests-2015_xx_xx.log".

The following entries in the log file is filling the tables in the database until it comes to a standstill.

Unfortunately i found no configuration option in the vsc plugin, which stops these log entries or reduces them.
I do not know why these entries are created or for which they are needed.
I would be very grateful if someone could propose a solution for it.
Thank you very much
