thanks for reply Glenn.Sounds like you don't have enough free memory for it to
run. Try running "free -h" to see if you have enough memory available. You may
need to shut down some other services first. -> my system free memory status is
normal.MemTotal: 1027004 kB MemFree: 236040 kB Buffers: 0 kB Cached: 278888 kB

what does mean??
dhcrelay: Can't initialize context: not enough free resource ->opensocket
function is return ISC_R_NORESOURCES. (bind/bind-9.9.5/lib/isc/unix/socket.c)I
think it's the fd problem with the socket, but I don't know when it happens.
Thanks.

Yeah, the free memory looks completely ok, so that's not it.
Do you by chance have dhcpd also running on the same system? I don't
believe you can have both dhcpd and dhcrelay trying to open the socket
on the same interface. So if you have both then each needs to listen on
different interfaces.
Failing that perhaps looking at the source might give some hints. Do you
have any limits on open files for example. ulimit -n will show the
permitted number of open files, which includes sockets.
regards,
Glenn
