Excess FD errors #250
Milestone
Comments
I don't think this is a regression. ZDNS does preemptively open thr FDs at
the start now. You either need to decrease the number of workers or
increase the number of the FDs you can open.

FATA[0000] unable to create socketlisten udp 10.0.0.184:0: socket: too many open files
I assume this isn't expected, so I'm wondering if this is a regression. I
could of course be using it wrong, too! Happy to provide any additional
information if it would be helpful.

Capping the number of worker threads did the trick. Maybe bumping the default down to something smaller would be useful? The fix wasn't obvious to me 🤷 If not, we can close. |
At the very least we should output a useful error so that the user knows what's going on and how to fix |
