tomcat 8.5 broken pipe increases open files on ubuntu AWS
If there is slow response from db I see this stack trace and the open files
goes high and the only way to open files go down is to remove the instance
from Amazon load balancer.
Is there a way to keep the open files low even when Broken pipe error is
thrown ?
