I have lots of zombie jobs in the redis

Created by: jalateras

I have about 20K zombie jobs that look something like this

1) "data"
2) "{\"url\":\"http://www.xxxxx-in.com.au/show/xxxxxx/videos/xxxxxxxx/\",\"plugin\":\"javascript\",\"timestamp\":\"2014-08-05T04:19:06.935Z\",\"timezoneOffset\":240,\"sessionId\":\"3323473c-9a2e-21ad-5cd4-2127c4f51863\",\"publisherId\":\"8b746d3b-b05e-45b4-a8ae-bfbeb097affe\",\"mediaId\":\"3706240057001\",\"mediaDuration\":616.72,\"events\":[{\"timestamp\":\"2014-08-05T04:19:06.934Z\",\"event\":\"PROGRESS\",\"fromPosition\":460.6,\"toPosition\":520.6}],\"createdAt\":\"2014-08-05T04:19:06.542Z\",\"ipAddress\":\"24.114.58.95\",\"remoteAddress\":\"6ec79e53f022f8dc51490289a0d623a3\",\"userAgent\":{\"browser\":\"Safari\",\"version\":\"7.0\",\"os\":\"OS X\",\"platform\":\"iPhone\"},\"deviceId\":\"58a8d01f6b00e9d5d0f64872388b1ebf\"}"
3) "progress"
4) "0"
5) "opts"
6) "{}"
redis 127.0.0.1:6379> hget bull:oztam.collect.incoming:2702190 progress
"0"

When the server restarts these jobs are not being processed. How should these zombie jobs be handled?
