[Mediawiki-l] Job Queue Never Decreasing

[APseudoUtopia]

I'm running MW 1.15.1. I'm having a problem with the Job Queue. I
noticed that on Special:Statistics, the job queue length is always
1,200. Ever since I started the wiki, it has been the same thing -
1,200 - the entire time. The wiki does have a light load, so I tried
setting $wgJobRunRate to a higher number such as 5, then browsing the
site a bit and monitoring the JobQueue length. Nothing changed.

How can I get more information on this? Such as, what jobs are
actually in the queue? Why aren't they running?

Thanks.
