I pulled that log into the http://gceasy.io website. This is a REALLY nice way to look at GC logs. I do still use gcviewer for in-depth analysis, but for quick examination and locating trouble spots, that website is top-notch. Based on what I saw, I don't think you're running out of heap. It's more likely that it's too many file handles or limits on the number of processes/threads that can be started. Most operating systems limit both of these to 1024 by default. If you're on a non-windows OS (which I think is probably likely, given that you have said Solr is crashing), change to the logs directory and type this command: grep OutOfMemoryError `ls -1tr solr.log*` If it finds anything, it should give you the most recent error last. Thanks, Shawn
