What? I hope you are not confusing the USB/PXE extension pack with the client piece, emulators/virtualbox-ose-additions. -- +-------------------------------+------------------------------------+ | Vennlig hilsen, | Best regards, | | Trond Endrestøl, | Trond Endrestøl, | | IT-ansvarlig, | System administrator, | | Fagskolen Innlandet, | Gjøvik Technical College, Norway, | | tlf. mob. 952 62 567, | Cellular...: +47 952 62 567, | | sentralbord 61 14 54 00. | Switchboard: +47 61 14 54 00. | +-------------------------------+------------------------------------+ From owner-freebsd-questions@FreeBSD.ORG Mon Apr 13 09:34:43 2015 Return-Path: <owner-freebsd-questions@FreeBSD.ORG> Delivered-To: freebsd-questions@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) (using TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits)) (No client certificate requested) by hub.freebsd.org (Postfix) with ESMTPS id 3851587B for <freebsd-questions@freebsd.org>; Mon, 13 Apr 2015 09:34:43 +0000 (UTC) Received: from formentor.toolfactory.net (pina.toolfactory.net [213.97.158.39]) by mx1.freebsd.org (Postfix) with ESMTP id AEB20C5E for <freebsd-questions@freebsd.org>; Mon, 13 Apr 2015 09:34:42 +0000 (UTC) Received: from localhost (localhost.localdomain [127.0.0.1]) by formentor.toolfactory.net (Postfix) with ESMTP id 43E52177767; Mon, 13 Apr 2015 11:34:41 +0200 (CEST) Received: from formentor.toolfactory.net ([127.0.0.1]) by localhost (formentor.toolfactory.net [127.0.0.1]) (amavisd-new, port 10032) with ESMTP id egbBdVwalEig; Mon, 13 Apr 2015 11:34:40 +0200 (CEST) Received: from localhost (localhost.localdomain [127.0.0.1]) by formentor.toolfactory.net (Postfix) with ESMTP id 8C9BC177865; Mon, 13 Apr 2015 11:34:40 +0200 (CEST) X-Virus-Scanned: amavisd-new at logpmzimmta01v.toolfactory.net Received: from formentor.toolfactory.net ([127.0.0.1]) by localhost (formentor.toolfactory.net [127.0.0.1]) (amavisd-new, port 10026) with ESMTP id UBoZVVDxQ7I8; Mon, 13 Apr 2015 11:34:40 +0200 (CEST) Received: from xorrigo.toolfactory.net (unknown [192.168.2.210]) by formentor.toolfactory.net (Postfix) with ESMTP id 6A3F1177767; Mon, 13 Apr 2015 11:34:40 +0200 (CEST) Date: Mon, 13 Apr 2015 11:34:39 +0200 (CEST) From: Raimund Sacherer <rs@logitravel.com> Reply-To: Raimund Sacherer <rs@logitravel.com> To: opendaddy@hushmail.com Message-ID: <256156537.124536215.1428917679223.JavaMail.zimbra@logitravel.com> In-Reply-To: <20150411151945.B265FA01DE@smtp.hushmail.com> References: <20150409034121.7D7C720395@smtp.hushmail.com> <CADqw_gL6b4fYyda9GzKt4BGv=d=sASttf4bp2_W+6JnuKQUCjg@mail.gmail.com> <20150409113928.EE31F401E4@smtp.hushmail.com> <CADqw_gK8-bxeNTYw4ATQnSM-w0iNBVWma83hMScdbsCwzEGxEw@mail.gmail.com> <20150409185801.1B1E9401E3@smtp.hushmail.com> <369199529.123430074.1428656504549.JavaMail.zimbra@logitravel.com> <20150411151945.B265FA01DE@smtp.hushmail.com> Subject: Re: Initial request to server extremely slow after longer periods of inactivity MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable X-Originating-IP: [192.168.2.213] X-Mailer: Zimbra 8.0.8_GA_6184 (ZimbraWebClient - SAF7 (Mac)/8.0.8_GA_6184) Thread-Topic: Initial request to server extremely slow after longer periods of inactivity Thread-Index: keQzV9AcwoAgwxW8FaOn6icJF8wqqQ== Cc: freebsd-questions@freebsd.org X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.18-1 Precedence: list List-Id: User questions <freebsd-questions.freebsd.org> List-Unsubscribe: <http://lists.freebsd.org/mailman/options/freebsd-questions>, <mailto:freebsd-questions-request@freebsd.org?subject=unsubscribe> List-Archive: <http://lists.freebsd.org/pipermail/freebsd-questions/>; List-Post: <mailto:freebsd-questions@freebsd.org> List-Help: <mailto:freebsd-questions-request@freebsd.org?subject=help> List-Subscribe: <http://lists.freebsd.org/mailman/listinfo/freebsd-questions>, <mailto:freebsd-questions-request@freebsd.org?subject=subscribe> X-List-Received-Date: Mon, 13 Apr 2015 09:34:43 -0000 ----- Original Message -----=20 > From: opendaddy@hushmail.com > To: "Raimund Sacherer" <rs@logitravel.com> > Cc: freebsd-questions@freebsd.org > Sent: Saturday, April 11, 2015 5:19:45 PM > Subject: Re: Initial request to server extremely slow after longer period= s of > inactivity > Hello, > On 10. april 2015 at 9:01 AM, "Raimund Sacherer" <rs@logitravel.com> wrot= e: > > > >Then what I would do in your case is open a few ssh sessions, run > >top with cpu focus in one, top with IO focus in another and in a > >third i would take a tcpdump written to a file.

Yes, that could be, but you would be able to rule it out rather quickly, if= you do not seem to get the system in the "unresponsive" state then I would= execute them in a screen or tmux session so they are available for you to = check out later. In this case a top won't do you much good and you have to = use some form of vmstat or similar to check out what had happened (cpu, pag= ing, interrupt storm, context switches, IO-wait, etc.). If none of those in= dicates problems, and the tcpdump does not reveal DNS problems it may be an= issue with the VPS host (if you use a virtually shared hosted service).=20 Best Ray > Also, how can I do stuff like `traceroute` or `mtr` knowing beforehand th= at > the server is indeed unresponsive?
