Hmm - are all the actions (action field in the table) related to indexing?  I'm certainly no expert on the intricacies of it all, but I do know that, for instance, the IRUS plugin uses the event queue to record when it was unable to contact the main IRUS servers to report a download, so it can attempt to do so at a later date.
I'll leave it to Adam or someone with a more in-depth knowledge of eprints events to advise as to whether you could simply clear the event queue, or whether that would cause you subsequent problems...

We don't.... but then, we don't need to index anything as we have no text-searching (and why waste clock-cycles creating full-text searching we won't use)
