Where did the g* files in the ~X.400/tmp directory come from?
Hewlett Packard has identified a problem where FTBP attachments can result in files being left in the ~X.400/tmp directory, i.e. for each FTBP one temporary ‘g’ file will be created that may not be removed after processing has completed. The workaround for this problem is simply to schedule a cron job that clears up ‘g’ files in the ~x400/tmp directory that are old. For example, more than a day old.
