Hi Monti, As pointed out there is a huge gap of no information. There are two primary possibilities. One is that something about your resources is depleted. As Shawn has pointed out... watch them as you start up. Two, Solr is somehow locked or waiting on something. Since there is no information at the INFO level you can either throw your logs into DEBUG level and pray to god you see something relevant in the noise. Or, you can run a thread dump after you've hit your gap in time and see what the server is doing at that moment. My recommendation is to do the latter. I'd also wonder about that 0 cores found entry as well.
