I have a vanilla installed SLES9 system with no applications runnig as of yet. Everything is default (except I disabled the ldap server and set the default run level to 3 so no X processes are running either) However, it seems to be using a rather large amount of memory compared to other distro's. Here is a snapshot from top: (I know top is not an accurate means to getting this info but it is always relatively close) top - 23:52:38 up 1:59, 1 user, load average: 0.00, 0.00, 0.00 Tasks: 52 total, 2 running, 50 sleeping, 0 stopped, 0 zombie Cpu(s): 0.2% us, 0.0% sy, 0.0% ni, 99.8% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 1034168k total, 728752k used, 305416k free, 74364k buffers Swap: 1049528k total, 0k used, 1049528k free, 516876k cached When the system first booted memory usage for around 500mb (still high) but during it's 2 hour of uptime it has grown to 728mb, by itself, with no system activity. When I look at 'ps -aux' there doesn't seem to be any single process using a large amount of memory. This system is a dual Xeon, 1gb memory, SysKonnect gigabit NIC, 2x36gb SCSI disks with 3 Raid 1 devices. (/boot, swap, and /) This just seemed like a large amount of memory being used with no applications running other than the default services. Thanks for any info, CC
