PREPBUFR Tables Error



I have recently been attempting to convert my little r files into bufr files using the obsproc.exe tool. I am able to convert all my little r files into the .4dVAR files, however whenever I try to convert those to a bufr file (so I can then use other bufr files in my data assimilation), I get this weird error that says: "
A file is already connected to unit 10which is needed for the PREPBUFR tables
Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG"
If anyone has any ideas please let me know. I have attached a log file containing this error as well as the namelist.obsproc file. I can also attach my data file if need be.

Thank you,
Jeremy B.

I believe I figured it out. Please correct me if I'm wrong, but bufr files really only contain one timestamp, so trying to write multiple timestamps didn't work. What I did instead was convert the bufr file to little r, and ran WRFDA that way and that works.
