I am using the utility of wait and notify and for that I have used Distributed map cache client service and Distributed map cache server, but somehow I am getting an error in service "too many open files", I have even increased the "nofile" in node. In the same instance but in another nifi flow I am able to use this functionality but if I do configure this service in another parallel flow I face issues. Below I am attaching the screenshot of conf and error. any help would be appreciated.
