Data Server Connection Problem in MII 12.1 Version.

Question

Hello Experts,
I am using two instances of MII 12.1.8 Build (20), at which am recently facing problems in the Data Server Connections.
Am not able to connect to the Data Servers using connectors [IDBC, Virtual IDBC].
When I checked the status of the servers, it is showing the status as running but there is no available connections.
When trying to create the query templates I dont get the available tables list populated too.
The driver details for jdbc used are the default ones,
For IDBC,
JDBC Driver : com.inet.tds.TdsDriver
ServerURL : jdbc:inetdae:<ip_addr>:1433?database=<db_name>&sql7=true
For virtual IDBC,
ServerPackage: com.sap.xmii.Illuminator.connectors.Proxy
The error that we got in the LogViewer.
Log Record Details   
Message: Unable to get a connection from the pool

Category: /Applications/XMII
Location: com.sap.xmii.Illuminator.tools.database.ConnectionHolder
Application: sap.com/xappsxmiiear
Thread: Thread[HTTP Worker [@2017129105],5,Dedicated_Application_Thread]
Data Source: j2ee\cluster\server0\log\applications_00.log
Arguments: 
DSR Transaction: 603b4f9bad3011e0c6f000001b57fb82
Actually the connections were working fine, in both the MII instances am working on (of the same build).
Now they both have gone down, all of a sudden
Please suggest the checks and corrections, I should do to overcome this hurdle.
Thanks for any help in Advance.
