This chapter lists problems that may occur with McIDAS-XCD. Under each symptom or error message, possible solutions are given. The problems discussed here are:
The user reports no real-time data, or the ingestor status display is red.
The file system may be full. You can use the McIDAS-XCD commands QRTMDG and DELWXT to delete older text, point files and grid files. Do not delete any files for the current day.
Check for an obstruction in the antenna and verify that all receiving hardware is working properly.
Contact your source provider to see if they are having a problem with the broadcast.
The GRIB decoder can't file grids if it can't find RTMODELS.CFG, which contains information about real-time grid file locations.
The file RTMODELS.CFG should reside in ~mcidas/data when McIDAS-XCD is installed correctly. Either the decoder can't reach the file or it is missing. If it's missing, recreate the file or copy a new version of the default file from ~mcidas/xcdversion/data/RTMODELS.CFG (where version is the version number, e.g., 2005).
When more than one ingestor is trying to read the same circuit, text data may be missing or text output garbled. If you are decoding grids, grids may be missing.
Only one ingetext process should be running for each text circuit, and only one ingebin process should be running for each binary circuit. Check the number of ingetext and ingebin processes running.
If this process doesn't work, check for an obstruction in the receiving antenna.
