Scripts with dreamhost ps


I am using dreamhost ps, with a 30/300 limit. I am trying to automate a backup of my joomla site, using tar to backup the files. However, whenever I run the tar, it errors out on me with the following:

tar: Error exit delayed from previous errors

I don’t see any previous errors, and it doesn’t appear that I’m getting anywhere near my purchased limits, and disk space is plentiful, so I’m at a loss.

Anyone seen this before?
