I am running the backup script labelled "A Simple Shell Script Method like above, but with rsync over ssh" from http://wiki.zimbra.com/wiki/Open_Source_Edition_Backup_Procedure. every time it runs on a install that i did, It will stop 2 hours afterwards. I have multiple servers running and it only happens to the one. They all have the same software as the one having the issue. The only difference between all of them is the amount of email per user and the number of users. I have installed the latest patches for zimbra 7.1.1 and Centos on this server. Looking through the logs doesn't show anything either other then entries stop when this occurs. any help in figuring out where the issue is would be much appreciated.
