Cumulus Support

Hi All
I have every thing working and realtime.txt uploads and every thing on the webpage and other apps works great. Then after a day or 3 (varies) Realtime.txt does not update, no FTP errors on Cumulus and everything else seems OK like today's info just the real time not working. I go to my FTP program delete Realtime.txt and then everything works again for a day or 3.
Any ideas why this would happen when everything else updates OK. seems that there is no pattern to it.
Any help would be great
Thanks in advance

Turn on ftp logging, and then when the problem occurs, look at realtimeftplog.txt. You might want to delete that file from time to time until you hit the problem, as otherwise it may get rather large.
