This is very weird, looking at /usr/src/lib/libc/rpc/svc_run.c, around line 64:
void
svc_run()
{
#ifdef FD_SETSIZE
fd_set readfds;
#else
int readfds;
#endif /* def FD_SETSIZE */
for (;;) {
#ifdef FD_SETSIZE
readfds = svc_fdset;
#else
readfds = svc_fds;
#endif /* def FD_SETSIZE */
switch (select(_rpc_dtablesize(), &readfds, NULL, NULL,
(struct timeval *)0)) {
case -1:
if (errno == EINTR) {
continue;
}
perror("svc_run: - select failed");
return;
case 0:
continue;
default:
svc_getreqset(&readfds);
}
}
}
I have grepped the entire -stable kernel source for ECHILD, and it is only
used in kern/kern_exit.c, in wait1(). So I have absolutely no idea
why select is returning ECHILD. This could be a hardware problem. Anyone?
