Hi Qihan,

This is an interesting error that we haven't seen before.  However, it is directly related to user-limit on number of open files.  You can check this thread https://forums.gentoo.org/viewtopic-t-464088-start-0.html <https://forums.gentoo.org/viewtopic-t-464088-start-0.html> that has a similar error and has a suggested solution.

From the log I see that your application (or applications) keep connecting to NFD, with ~1023 (before crash) active apps.  I wonder, is it your real intention or it is a some sort of an accident?  I mean, do you really want that many applications to be active?
