Hi Pete, I am not aware of any issue with multiple instances of gdcsv running, my only thought is if more than one instance is writing to the same file, that could obviously result in not seeing the file written correctly. Is there anything which points to the source of the problem? A particular model, date/time, parameter to isolate? Perhaps if I could hear more details about how gdcsv is being used, how many instances, how frequently they run, etc. -Michael James Unidata > We are using gdcsv in a multitasking environment - launching many > scripts in the background running gdcsv.
