Best guess is that smbd knows the kernel supports oplocks
but the failure is caused by the failure to register the
signal handler (perhaps due to the mounted nfs file system).

Ther relevant code is :

struct kernel_oplocks *linux_init_kernel_oplocks(void)
{
~   ...
~   act.sa_handler = NULL;
~   act.sa_sigaction = signal_handler;
~   act.sa_flags = SA_SIGINFO;
~   sigemptyset( &act.sa_mask );
~   if (sigaction(RT_SIGNAL_LEASE, &act, NULL) != 0) {
~   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
~      DEBUG(0,("Failed to setup RT_SIGNAL_LEASE handler\n"));
~      return NULL;
~   }
~   ....
}
