Jenkins 2.73.3
After upgrade to 2.73.3 we noticed that after a few days Jenkins becomes unresponsive and gives "too many open files" error. The only way to overcome the issue is to restart the instance.
The File Leak Detector Plugin shows that most of the open handles are of this kind:
#1 /opt/jenkins/scripts/groovy-scripts/lib/vijava-5.1.jar by thread:Executor #1 for master : executing Test_Register_FitNesse_Slave #445211 on Mon Nov 27 16:15:27 CET 2017

Test_Register_FitNesse_Slave triggers a Groovy script and adds '/opt/jenkins/scripts/groovy-scripts/lib/vijava-5.1.jar' to the classpath. Also that job is triggered quite often.
Before the upgrade (on 2.46) we didn't observe such behavior.
