Memory consumption is high on my server

Memory consumption is high on my server 
SQL server is installed on my server and my database is SAP database i.e Data is coming from sap server.


there is lot of query in sleeping session.
is this query can cause memory high.

SPID	 Status   	DBName	    Command           CPUTime	   DiskIO
52	sleeping        MYDB	 AWAITING COMMAND	52284	    66383

all following queries are in above given format and is sleeping stats and most of queries have high disk IO


should i kill all queries which are in sleeping mode.
if i kill these sleeping session. is there any impact on SAP users.
