Values of some variables set to zero/near zero.

[imcslatte]

Describe the bug
The variables of some variables in my ERDDAP dataset are set to zero/ near zero for requests of more than 1e7 rows.

To Reproduce

I ran into some unexpected behavior for a dataset we have on our ERDDAP server.

https://tds.marine.rutgers.edu/erddap/tabledap/CORA_Profiles_ECCOFSgrid.html

If I set the parameters to extract data from 2019/06/01 to 2019/10/01:

https://tds.marine.rutgers.edu/erddap/tabledap/CORA_Profiles_ECCOFSgrid.nc?time%2Clatitude%2Clongitude%2Cdepth%2Cprovenance%2CI%2CJ&time%3E=2019-06-01T00%3A00%3A00Z&time%3C=2019-10-01T23%3A54%3A00Z

The values in the variable provenance (range 800:809) after row 1e7 in the file are set to zero or near zero. The same goes for I and J. The other variables are fine.

If I switch to the time period 2019/09/15 to 2019/10/01:

https://tds.marine.rutgers.edu/erddap/tabledap/CORA_Profiles_ECCOFSgrid.nc?time%2Clatitude%2Clongitude%2Cdepth%2Cprovenance%2CI%2CJ&time%3E=2019-09-15T00%3A00%3A00Z&time%3C=2019-10-01T23%3A54%3A00Z

The values that were set to zero previously. are now within the expected range.

In addition, I checked the source files, and there are no values outside the expected range. The values also look fine if I pull up a time series of the entire dataset as an ERDDAP graph.

Expected behavior
I expect all the values in the data set to be returned for a given query.
