Master.csv missing calls

Hi All,

I have experienced an odd issue where my masters.csv file is missing out call, primarily inbound to its output, i can see the calls in the asterisk CDR database fine but they do not seem to be present on the file archive the file every hour but the missing calls are timed any time in the hour period that the file is in use, there seems to be no pattern to the missing calls in terms of destination, context, or channels which would suggest it is perhaps not a configuration issue.

has anyone experienced issues like this before?

Kind Regards
Jason
