Message Storm Knocks NYSE Offline 163

ninjee writes "The New York Stock Exchange is re-examining its network after it was forced to close four minutes early at 3:56pm on Wednesday (1 June) because of a communications glitch. Trading opened on time (09:30 EDT) the following morning but the outage irked traders and raised questions about the reliability of a network described as 'ultra reliable' following improvements made in the wake the September 11 terrorist attacks. The outage stemmed from a fault in a system designed to distribute market data and operate computer trading systems. NYSE Chief Executive John Thain said that both the main system and its backup were swamped with error messages, Reuters reports. He added that the exchange would carry out remedial work designed to prevent any repetition of the problem."

          I don't see why it's ironic. As uninformed as some slashdot posts are, there are also a lot of users who recognise that copyright makes a lot of sense, and is actually useful. It's the enforcement of copyright that allows the GPL and the GFDL to work. What many people here do complain about is the never-ending extentions of copyright, arguably against the general public interest, and allegedly because corporations have bought off politicians.

          This may be a joke, but it was copied verbatim without providing the copyright notice, which is required [wikipedia.org] by the GNU Free Documentation Licence. It's a copyright violation, and to ignore it as irrelevant would be hypocritical and ironic in itself. (Not to mention illegal.)

    • Designing a system to not fail means that it will fail in a way that you didn't plan for.

A spoon is ultra-reliable and I've never suffered a spoon failure ... but I can't fix a car transmission with a spoon. My spoons could become 100 times more unreliable, and I'd barely even notice. They're too simple to even care about.

      A "message storm" is a storm of data that overwhelms a system, kind of like a DDOS, but legitimate traffic. In this case it sounds like a large number of error messages overwhelmed the message queueing system (probably MQ from IBM), which likely set off an even larger storm of error messages when backed up messages started to expire.
      • Did you notice the ticker going "PR0N... V1AGRA... DIPLOMAS... PR0N... V1AGRA..."?

      • I've never understood the corprorate programmers' obsession with purchasing message queue systems like MQSeries. You can design and code something that does the 90% that you actually need of what MQSeries does yourself in a week tops. MQSeries is so universal and overly complex for what most people want out of it, which is just reliable transactional networked message queueing with the options of in-order delivery, multiple queuers and dequeuers, and disk persistence.

          shoot, I'll just go and whip one up before bedtime.

      • something to keep in mind about systems like these is that they are basically handling intentional DDOS attacks all day. what i mean is, picture thousands of traders all clicking away at a computer screen at the exact same millisecond (kind of like a slashdot effect), frequently sending multiple orders each. this often happens because traders listen to the same news and trade off the same events. so the exchange's systems are designed to handle major DDOSing all day. and they are required to handle the requ

    as a trading engine developer/support guy for a financial firm in ny, i can't stress enough what a pain in the ass this was. the day after the nyse crash, it took hours upon hours of verifying (by hand) trades that the nyse says we were filled on that we never say (because all nyse trading lines were down).

    this type of 'message flood' occurs from time to time, but not on the nyse in a while. it's generally the ecms trading otc stocks that have rouge programs blast orders in an infinite loop. when this happens to an ecm, they slow down but generally don't lose the ability to trade. the nyse, who toutes the importance of their rapists^H^H^H^H^H^H^Hspecialists because they add 'stability' to the system, was dead in the water. this crash goes to show how useless the specialists really are - without the technology working, they can do nothing. if this is the case, why not just replace them altogether with electronic trade matching?

    interestingly enough, the nyse announced mere months ago that they are 'merging' with archipelago - a large ecm. perhaps this merger will be the beginning of the end of the specialists.

    I wonder if NYSE uses tibco rendevouz for their message transport "bus". My work uses this software, and our usage of it has stressed it to extremes and you can end up with message storm issues.

    FYI this system is a multicast-based publish-subscribe system. The multicast thing tends to be a wash IMHO, especially since many people use it for queues, rather than true 1 to many messaging.
    • I worked at tibco, but not in the messaging side of engineering - it's only a smallish part of what they do. Here's what I remember, modulo time and lack of coffee:

      - NASDAQ uses tibrv (formerly Rendezvous). This featured a lot in tibco's pitch about reliability/scalability etc. NYSE, I *think*, uses MQ Series.

      - Rendezvous used to only run over IP broadcast, with software "router" daemons for crossing subnets. This has not been required for years now - remember, the history of Rendezvous stretches bac
      • Ah yes, we've seen the multicast group table problem. Basically you run into it and your system instantly crashes and suffers huge difficult to recover problems. I wasn't directly involved, but we have put in place migration paths away from tibco. Of course we were doing several things wrong:

        - Dont have HUGE subject names - significantly reduces performance I have been told.
        - dont use multicast for point to point RPC-like services.

        Of course its intensely attractive since you can just run a program, not
    • Tibco's implementation definitely leaves a lot to be desired. Their success has always came from their ties with Reuters (who used to own a huge stake in the company) and thus their use in high profile environments. Its never been because of their technology.
  • This was actually most likely the result of a multicast or "slow consumer" storm. In a multicast network environment, often desktops are overloaded by all of the filtering they must perform (multicast sends nearly everything to everybody). Sometimes some desktops will miss a packet and ask for a retransmission. Often, this involves retransmitting in multicast-form - that is to all of the consumers. If this happens too many times, you get a storm. No matter what the NYSE does (unless they buy our technology

    I work in Technology for a Wall Street firm (you've heard of them). Stuff like this happens all the time -- systems go down and are usually back up pretty quickly, some route to some exchange will bounce for a few min. This time it was worse in that it affected NYSE and not one of the smaller exchanges at the end of the trading day. If you look at any graph showing trading volumes, the last few minutes of trading are always the heaviest.

    99.9% of the time, things bounce back very quickly and with the exception of a few internal emails, nobody cares, things go on.

      This contrasts with my previous experience at a struggling airline company, where such failures were tagged with a price tag and flagged as "never, ever do this again". :-) Even if they weren't struggling, though, t
