I'm running Zimbra on Ubuntu 6.06.2 LTS. The normal scheduled backups were running every night with the default schedule. One night the server load went incredibly high and all services stopped responding. Since then every night when the backup runs the server stops responding. I unscheduled all backups and tried to run one manually in a new directory with the same results. The server is all installed in one partition that is only 20% full.
I have been unable to find anyone else with this problem or figure out a fix. It seems like the backup process is hogging all the resources and not being niced. No configuration changes were made to the server. I'm at a lost for how to get backups running without taking down the server now. Any help in pointing me in the right direction would be appreciated.
