Fwd: ECMP BGP issue of more than 16 paths

Yeah in version 1.6.0, it installed with only one path even if i just
specify "merge paths"

After killing the bird process, it showed as "netlink receive error No
buffer space available (105)"

When I upgraded to 1.6.2, "merge paths yes limit 255" command worked with
all the paths installed. But the bird process occupying the CPU and memory
, the kernel crashed with out of memory issue.

Not sure how to proceed with this :)
