When attempting to download market summary files, I receive an error:

[my prefix],E,Incomplete file from server. 521309/615706,

The error seems to come and go. At the moment, if I ask for NYSE 5MS it works fine. If I ask for NASDAQ, it does not.

Based on recent experience, I'm guessing that if I wait a few hours, it will go away.

Any suggestions?

I'll have to try again to reproduce the problem, which I haven't been able to do so far. I may also ask affected customers if they're willing to do some logging to try and capture a log with the issue.

As part of my process, I am downloading a 5 minute market summary from NYSE, NASDAQ, and OPERA. I have yet to see the NYSE summary fail. The failure of both NASDAQ and OPERA I have seen, and always with different statistics. That would seem to indicate that size could be the issue, as the NYSE summary is always smaller. Perhaps there is a timeout that is a bit too restrictive? As a side note, latency at my location may be a bit high (throughput is reasonable), as I am currently in Panama.

Let me know if you would like me to do some logging.

FYI: As the problems seem to be the same, (as mentioned above) I will post my findings at: http://forums.dtn.com/index.cfm?page=topic&topicID=5649
