Hi Erick, We have custom code which are schedulers to run delta imports on our cores and I have added that custom code as a jar and I have placed it on server/solr-webapp/WEB-INF/lib. Basically we are fetching the JNDI datasource configured in the jetty.xml(Oracle) and creating connection object. And after that in the finally block we are closing it too.
Never faced this issue while we were in solr5.2.1 version though. The same jar was placed there too. Thanks, Srinivas On 06-Mar-2020 8:55 pm, Erick Erickson <erickerick...@gmail.com> wrote: This one can be a bit tricky. You’re not running out of overall memory, but you are running out of memory to allocate stacks. Which implies that, for some reason, you are creating a zillion threads. Do you have any custom code? You can take a thread dump and see what your threads are doing, and you don’t need to wait until you see the error. If you take a thread dump my guess is you’ll see the number of threads increase over time. If that’s the case, and if you have no custom code running, we need to see the thread dump.
