Summary0006433: [BUG] trying to modify fd -2 in fd table, but MAXCONNECTIONS is 16384
DescriptionTwo users reported getting this message. Have asked if anything related occurs just before or after it.

One user said:
Since upgrading to 6.1.7 I am occasionally seeing bunches of the following error message from the server: io.BUG_FD_SETSELECT_OUT_OF_RANGE [error] [BUG] trying to modify fd -2 in fd table, but MAXCONNECTIONS is 16384
Syzop: I'm not sure if it would be related, but about 30 seconds before the errors, DroneBL blocked an IP address from connecting...that's the last thing I see in the logs before three of those error messages, very strange. (So far I have not seen it enough to figure out a pattern, thankfully :) )

Other user, Blackbishop:
Saw no such pattern, no user activity for more than 30 mins before the message(s) and nothing after it for hours.
(Exact version unknown at the time of writing...)
TagsNo tags attached.

At the moment it is "just" an annoying message that occurs sometimes.

I'm setting this as private so i can more freely paste versions and possibly confidential output from users.

Version output from users censored out so this can be public.
