Cisco IPSEC SA increasing "send error"?

Hi Guys,

I'm running DMVPN with ipsec profile but currently having issue in connectivity from different sites. What would be the issue if ipsec not encapsulation/decap packet, also noticed that #send errors 17939 is increasing. no other parameters/stats?

​

Phase 1 is established.

sh crypto ipsec sa

interface: Tunnel1

Crypto map tag: Tunnel1-head-0, local addr xxxx

protected vrf: (none)

local ident (addr/mask/prot/port): (xxxx/255.255.255.255/47/0)

remote ident (addr/mask/prot/port): (xxxx/255.255.255.255/47/0)

current_peer xxxx port 500

Both local and remote address seem ok same with the other side. anyone encountered this issue?

​

Kindly comment if need more information.
