mqueue full, please help

[Matt]

On my Raq4i I have over 1000 messages in my mqueue.  My RAQ is at a crawl.

Some have only this in them:

link_stat rsync : No such file or directory
rsync error: some files could not be transferred (code 23) at main.c(620)

Others contain this:

MDeferred: pursuit.deleted_for_privacy.com.: No route to host

What caused this and how the heck do I get rid of them?  Please help!

Matt
