I'm seeing two different things that hopefully someone can help explain. When downloading historical daily data for some options, I will get several lines (only one in this case) at the end of the file without a timestamp (and all of the quote values will be zero). This normally occurs if there aren't many days of option data and I end up requesting data before early-2000.
In addition, for the request
HD,ABT_QF,1000;
the quote retrieval stops without ever issuing the !ENDMSG!, !SYNTAX_ERROR!, or !ERROR! end-of-message token.
The missing timestamp line is shown below in bold.
2000-02-10 05:43:57,0.000,0.000,0.000,0.875,0,0
2000-02-09 05:43:57,0.875,0.875,0.875,0.875,0,0
2000-02-08 05:43:57,1.0625,1.0625,1.0625,1.0625,0,0
2000-02-07 05:43:57,1.3750,0.9375,0.9375,1.0625,0,0
,0,0,0,0,0,0
Any hints as to how to avoid this are greatly appreciated.
Is there a log of any kind on the IQFeed software that could shed some light on this issue?

P.S. I've seen this both with my own software and with the Java LookupClient, so it seems logical that it's either a problem on the DTN server side or the IQFeed software (which may include something interacting with IQFeed on my computer).
