I am getting below error while I am trying to content porter from my DEVtridion to TEST tridion.

    Unable to save Publication (tcm:0-230-1).
    Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.
    
    Error Code:
    0x8004033F (-2147220673)

If I see content portar logs, I can find these:

    <tcm:Line ErrorCode="8004033F" Cause="true">
    		<![CDATA[Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.]]>
    	</tcm:Line>
    	<tcm:Line ErrorCode="8004033F" Cause="false">
    		<![CDATA[A database error occurred while executing Stored Procedure "EDA_PUBLICATIONS_FINDBPCONFLICTS".]]>
    		<tcm:Token>EDA_PUBLICATIONS_FINDBPCONFLICTS</tcm:Token>
    	</tcm:Line>

What could be the reason, why my content portar is not able to get sql connection of my TEST server.
