Ok, I've compiled a new kernel with option MP_LOCKDEBUG uncommented on
GENRERIC.MP conf file.
After booting :
kern.version=OpenBSD 6.1 (GENERIC.MP) #1: Thu Jun 1 15:47:28 CEST 2017
[email protected]:/sys/arch/amd64/compile/GENERIC.MP
$ while true ; do ./a.out ; done
a.out: socket
a.out: socket
<- somewhere after this point, the server stop responding
Sending a BREAK via cu(1) does nothing.
