    Description

      It seems that Wookie opened too many files at the same moment or that Wookie did not close the open resources

      catalina.out

      This command "lsof -p 1720 | grep wookie | wc -l" returns 854 files opened by Wookie: It shows open files by Tomcat PID and then filter by Wookie app, I attached the result of the command "lsof -p 1720", the most opened files are ".wgt" files from "upload" folder, they are opened several times.
