When I do a TOP, the Performance Toolkit shows a spike to 90% of the cpu. When I ctrl-C out of top, it goes down to 32% (normal).
This one server is a memory hog. It uses Tomcat (on sles9 sp3) with 350 connections at one time (I do not own this server, I just set it up and we are currently rearchitechting it using sles10). When I do a PS, it pages on forever (actually 400+ processes). Would vdisk help in this situation (or maybe 1G on disk and 500M on vdisk or some variation) ? -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Adam Thornton Sent: Wednesday, February 28, 2007 10:47 AM To: [email protected] Subject: Re: Vdisk On Feb 28, 2007, at 9:28 AM, Levy, Alan wrote: > Unfortunately, I cannot do a TOP. It blows my server away. In the words of the inestimable Mr. Loaf: "Stop right there!" This is indicative of something very, very seriously wrong. I mean, *very* wrong. Now, maybe all you meant is the relatively innocuous "I'm logging in to the console on a 3270, and top expects a character-addressible display, and I don't have my terminal settings correctly configured such that literal '^c' functions as a break." And if you meant that, well, then, don't panic. Although your life is going to be a lot happier if you start logging in and doing stuff via ssh and a vt100-or-descendent terminal emulator. But if top actually "blows your server away"--you have real do-not- pass-go problems. > Here's a > free: > > total used free shared buffers > cached > Mem: 1550984 1547956 3028 0 1440 > 34324 > -/+ buffers/cache: 1512192 38792 > Swap: 1583792 220796 1362996 Yep, you're actually using all your real memory, and not for buffers and cache. The next question is, what are you using it for? Is it JVMs that have allocated huge stacks and heaps but aren't actually using them? Or are processes actually hitting most of that memory pretty often.
