Greetings George: I'm not sure that I see what the problem is. memTotalFree is reporting the amount of memory that you could (theoretically) allocate - the remaining available real memory and the available swap space. The numbers that you have listed from snmp seem to match the number from free pretty well. -Scott -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
