Basically means you have to dump out your whole boiling water pot and start again - never mind that you lost a whole jar of what you're canning! Using canning jars helps. You should never use old mayonnaise or other commercial jars for canning.
And Chey mentioned the extension service. I know the one here offers classes in canning, and will also test your pressure canner. They're a great resource if there's one near you. They used to give away a lot of information, now they charge, but it's reasonable.
