Result files disappearing

Hi,

I am creating a splunk alert trigger script which parses the output csv file. I am having a problem because the result file keeps disappearing. The trigger passes in the full path to csv file as one of the parameters. Sometimes my script is fast enough to read the file before it disappears, and sometimes it results in file not found. Why is that happening?

Thanks
