I have a Java process/app. When I run /usr/sbin/lsof -p on that java process, I see a lot of "can't identify protocol". Also, interestingly, File descriptors(FDs) are increasing at a very steady rate. And those FDs that are being created are having description as "can't identify protocol". So, is there any way to instrument/profile the java process so as to nail down who is creating that many FDs.
