--Boundary-00=_74cMHRu49pwLB76 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Content-Disposition: inline Hello; I'm running a qmailrocks install + DNS server here. Hosting 14 domains and their respective e-mail accounts. Everything seems to be working fine. The machine is: ------------------------------------------ FreeBSD 6.2-STABLE #0: Mon Sep 10 14:15:16 BRT 2007 CPU: Intel(R) Core(TM)2 CPU 6700 @ 2.66GHz (2669.94-MHz K8-class CPU) Origin = "GenuineIntel" Id = 0x6f6 Stepping = 6 Cores per package: 2 real memory = 3488481280 (3326 MB) avail memory = 3362598912 (3206 MB) FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 ------------------------------------------ When I turn the machine on/restart it, it starts off with around 2800 Mb free memory. I know that, in its course of work, a few of those processes do not properly return memory back to the system. The machine was last restarted exactly a week ago (last wednesday). Now 'top' shows me this: ------------------------------------------ last pid: 17204; load averages: 0.00, 0.04, 0.06 up 5+21:00:50 11:18:58 135 processes: 1 running, 132 sleeping, 2 zombie CPU states: 0.6% user, 0.0% nice, 0.4% system, 0.2% interrupt, 98.9% idle Mem: 379M Active, 1915M Inact, 256M Wired, 119M Cache, 214M Buf, 415M Free Swap: 5120M Total, 5120M Free ------------------------------------------ Here are my questions: Is this a "normal thing" to happen with memory in just one week? Does the '1915M Inact' means "zombie memory" (non-returned)? Is there a manual garbage collector i could run? What is your advise on what method I could use to precisely track down what program(s) is(are) causing this? I am attaching a png graphic of this.
