Error Starting management console."Too many sessions are open"

Dear Experts,

I have SAP PCo 15.0 connected to OPC DA source KEPServerEX V 5.15.

I am getting the following error when trying to open the management console.

Date|Time|Milliseconds|Machine|Thread ID|Process ID|Process Name|Event Type|Source|Event ID|Message|Stack Trace

31/07/2015|10:38:07|782|WVJ03003|8|92908|PCoSvcHost|Error|ServiceFaultManager|1910|Manufacturing Fault: REASON = SqlCeException Too many sessions are open.; SEVERITY = Fatal STACK TRACE:   at System.Data.SqlServerCe.SqlCeConnection.Open(Boolean silent)    at System.Data.SqlServerCe.SqlCeConnection.Open()    at SAP.Manufacturing.Connectivity.Data.DataConnection..ctor(Boolean openReadOnly)    at SAP.Manufacturing.Connectivity.InternalConfig.AgentInstance.Query(String name)    at SAP.Manufacturing.Connectivity.AgentBase.Initialize()    at SAP.Manufacturing.Connectivity.AgentBase.Start()|""

There are around 270 Agents configured in PCo.

I am able to start all the agents except two. When I try starting these agents I am geting the following error in the logs.

has anybody come across this kind of Error. Any quick response will be much appriciated.

Thanks and regards,

Sanjeev Sharma,
