Subject Re: Solr Issue

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.

Greg
