And if true, startup index creation thread are not released, sending the app in out of memory. ( https://hibernate.atlassian.net/browse/HSEARCH-3900?atlOrigin=eyJpIjoiZjB... ) Thanks Team, yes it was not an issue with Hibernate Search threads as we tested out application by disabling Hibernate Search and faced the same memory issue. That gave us confidence that its not due to Hibernate Search. But additionally we did increased the RAM allocation to our application and that too helped in rectification of memory errors. I’ve mentioned the same explanation on the SO thread ( https://stackoverflow.com/questions/61405928 ).
