Values of some variables set to zero/near zero.

[imcs...@gmail.com]

Hello, 

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. 

Obviously, we can simply reduce the size of our data requests. But it seems like strange behavior.  It is only for those three variables (provenance, I, and J). The others are fine. All the other variables are floats or doubles, and the problem variables are integers. 

Is there possibly a configuration issue?

The ERDDAP Version is 2.24

Could you create an issue on the Github for this: https://github.com/ERDDAP/erddap/issues

It'd be great if you could include the dataset configuration and some sample files to make it easier for us to reproduce the problem. If you can't include that, then at least the dataset type+configuration that you are using.
