Re: [Declude.JunkMail] OT Server problem

[Dave Doherty]

Hi Keith-   Buffer overflows can and do occur in non-OS software, usually when provoked by some clever hacker who has figured out the vulnerability - or a less clever soul who found out about it on a hacker site. They can shut down a variety of things on a computer. I'm not saying that's the only possibility by any means, but your scenario sounds exactly like what happened to me with that earlier version of Imail. I believe that problem was an IMAP vulnerability, but theoretically it can happen anywhere if the software is vulnerable.   -d     ----- Original Message ----- From: kztechinfo - cribellum To: Declude.JunkMail@declude.com Sent: Thursday, October 20, 2005 4:46 PM Subject: Re: [Declude.JunkMail] OT Server problem Dave,   Thanks for the response.  I am running Imail 8.2 with hot fix 2 installed.  I have been looking at installing 8.21 but I thought 8.2 hf2 was suppose to be stable.   Also,  If I go to Microsoft's update site it said there are no software/hardware updates available for my computer.  I am thinking if it was a buffer overflow wouldn't that be an issue with the hardware or bios?  It should keep a program from doing this.  I am hoping the upgrade to the bios will fix this.     Keith Zwick Cribellum, LLC 248-596-1901 ex301     ----- Original Message ----- From: Dave Doherty To: Declude.JunkMail@declude.com Sent: Thursday, October 20, 2005 4:30 PM Subject: Re: [Declude.JunkMail] OT Server problem Hi Keith-   Sounds like a buffer overflow problem that happened with an older version of IMail (8.1.4?). The machine behaved just as you describe. Be sure you have all the Imail updates as well as the ones for Windows.   -DaveDoherty  Skywaves, Inc. ----- Original Message ----- From: kztechinfo - cribellum To: Declude.JunkMail@declude.com Sent: Thursday, October 20, 2005 4:17 PM Subject: [Declude.JunkMail] OT Server problem Hi,   Sorry if this is off topic, or maybe it isn't.  I am running Imail 8.2 with declude 1.82 on a Poweredge server 1750, dual processors and 1 GB ram, internal Broadcom Netxtreme nic cards.  I have dns run on one internal nic and Imail on another.  It has happened before in the past but very rare that the Network card will stop responding.  The one with the DNS works fine but the other is non responsive and if you go to network connections it will just lock up trying to access the card properties, even though the rest of the box is runnning fine.  I have to do a hard reboot at this point to get the card to come back up.    I put the mail on the same card as the dns to see if the internal nic had issues but then that card locked up within 10 minutes.  I went out and bought an external card and put it in and the same thing happened after about 10 minutes of having the mail go through it.  I ended up going to Dell and downloaded an update for the nic cards and updated the flash bios and it stayed up this time.  I am hoping that is it.   However, the couple of times in the past two years this happened one reboot would fix the problem and would not come back for months.  I worried that this is the case again and it may happen again, sooner.   Has anyone experienced this?  I did applyl the microsoft patches sunday night but it ran fine for 4 days.   Keith Zwick Cribellum, LLC 248-596-1901 ex301
