Periodic Session Timeout for FIX session

Hi All,

We are working on WmFIX messages and completed FIX session configuration with Partners. When we sent FIX messages to Partner we are experiencing periodic session timeout. Once we initiate the Connect command from MWS (FIX Administration) the isConnected field will set as true and after some time it automatically change the status as false. Please let me know anyone experiece similar situation and what could be the root cause
