RE: [OT] Tomcat dies suddenly
Reminds me of a story from an old-timer friend of mine. This was back in the day of shuddertext-based terminals/shudder. The company he worked for had a military contract to install bunch of terminals in an office building at a local airbase. A few days after the workers moved in, his company got a call that something was wrong. About every few seconds, every terminal would get a string of random characters, each terminal getting a different string. After puzzling over the problem for a bit, he happened to look out the window and see the nearby radar dish sweep past the building at the same time the odd characters appeared. They checked a few random cables and found that the installers had used unshielded cables to save a few pennies. According to him, they spent the weekend wrapping the major cable bundles in foil as a stop-gap until they could come in and replace all the cables. -Original Message- From: George Sexton [mailto:geor...@mhsoftware.com] Sent: Sunday, February 14, 2010 10:58 AM To: 'Tomcat Users List' Subject: RE: [OT] Tomcat dies suddenly -Original Message- From: André Warnier [mailto:a...@ice-sa.com] Sent: Saturday, February 13, 2010 3:28 PM To: Tomcat Users List Subject: Re: [OT] Tomcat dies suddenly Caldarale, Charles R wrote: Since we must have by now exhausted all the normal causes of such errors, maybe we should recommend a) a visual inspection of the systems, to see if there are any pinsize holes, or paint flaking off or so b) the installation of a surveilance camera, to check if the SegFaults are synchronous with any visible phenomenon (sparks, Cerenkow radiation, etc.) c) moving the systems to the basement ?

Re: [OT] Tomcat dies suddenly
An ex-colleague of mine tells the story (which may well be apocryphal, but is good fun) of being called to an industrial estate in South Wales to debug a problem where floppy disks in the office would mysteriously wipe themselves - pretty much every floppy in the office, at the same time. It happened very occasionally, but with no hard disks and the company's financial accounts stored on floppies, this caused considerable problems. They'd been through the usual did-you-stick-it-to-the-filing-cabinet-with-a-fridge-magnet questions, and everyone in the office swore they were taking all reasonable precautions. Eventually she solved the problem when she saw the crane from the scrapyard next door swing a big load of scrap past the office window, all dangling from the large electromagnet at the end of the line... all she could do was recommend they moved offices or stuck a mu-metal cage round the room. - Peter On 16 February 2010 18:57, Mark H.

Re: Re:[OT] Tomcat dies suddenly
Chuck, The cases and even power supplies are very different. The T105 is destined to be a backup server and the T110 is supposed to be the front line guy.

That makes me think about something, specially since Carl mentioned that there are children involved. Maybe we should also investigate if the SegFaults are simultaneous with anyone specific entering the room where the servers are. Like someone bringing coffee or pizzas or so ? I swear that I have seen some long-running applications mysteriously fail as soon as some specific end-users approached a keyboard. They did not have to even touch the keyboard for this to happen. There are programmers like that too, for that matter. Surprise visits by big bosses are also among well-known triggering factors, as are demos to new users. But I think in this case we can eliminate the first one, since the problem happens several times per day. After the first couple of visits, the surprise element would tend to disappear. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

There have been 144 messages on this thread...and you have spent already months trying to solve the problem...I think it will be more cost effective to replace the boxes, run a standard JVM from Sun..and close this thread!
