Until recently the file was generated after the data collection was complete, but now the file is generated on the fly over several minutes. My IDL program is having a hard time with this! It's now loading the data file before it's complete, and sometimes before it contains any data at all.

Use two files. One file contains the data. The other file is only created after the first file is complete. Then by monitoring the signal file, your IDL code will know when it's safe to read the data file.
