Error 956; Maximum number of database sessions exceeded

[spacemonkey]

Could someone please advise me how I deal with this so I can allow users to log into the databases? How can I release the sessions?

I have 3 separate databases running - one publishing to the web using iwp; one publishing via php and the other does not publish to the web. There is only one user logged in at present and that person is accessing the database which is not publishing to the web!

Thanks in advance.
