I've come across an issue with the jira plugin, where after some time i get a bunch of "java.net.SocketException: Too many open files" errors. If I run 'lsof -p java-pid |wc -l' it returns 21330, forcing me to kill java and restart OpenNMS to get it working again. Attached is the output of 'lsof -p java-pid'
Also, when I stop the jira plugin everything returns to normal and the open files stays hovering around 2500.
OpenNMS version: 18.0.2
