The last line that I quoted above is the underlying problem here. Your OS has a limit on the number of processes/threads that each user is allowed to run. Solr has exceeded that limit, and so the operating system is preventing Solr from starting any more threads. The OS will need to be reconfigured to allow the user to start more threads. Just like OOME problems that actually have to do with memory allocation, program operation when a thread fails to start is *also* completely unpredictable. What version of Solr are you running, what OS is it running on, and exactly how did you start it? Thanks, Shawn
