my .config in 2.4.19 says

setsize is set only here
if (un_sock > setsize) setsize = un_sock;
and additionaly if client connects, here
if(curclient->id > setsize) setsize = curclient->id;
and setsize+1 is later passed to select()...
I ran strace on nano-X and this line does not seem right:
select(4, [3], NULL, NULL, {3813670912, 3785383936}) = -1 EINVAL
(Invalid argument)
-> exceptfds and timeout are bogus !?
I belive it should read
select(4, [3], NULL, NULL, NULL)
