One of the grid nodes status is 'Closed Busy', how to fix this?

[spitla1]

Since past two days we are receiving an alert that one of the nodes is not active. I saw the status using bhosts, it says 'closed_busy'. Does anybody know how to fix this please?

A status of closed_busy means that the node is not closed because it's out of job slots (closed_full) or closed because someone closed it (closed_adm), but that the node's metrics are above the scheduling threshold. In an LSF grid the lsload command should indicate which metric is exceeded with an asterisk.
