If you have a database or other program that uses shared memory this might be of concern, otherwise I would just ignore it. I checked 3 of my DL380s running RH 7.2 and they all had 0 for the shared column. <BR /><BR /> Fri, 29 Aug 2003 14:01:06 GMT https://community.hpe.com/t5/operating-system-linux/free-displays-value-of-shared-as-0/m-p/3059572#M6412 Dan Beeler_2 2003-08-29T14:01:06Z
