Thanks Vladimir for the quick reply !!
Its 3.4.x , but I'm wondering this problem is more the system / machine
level instead of GMond server level.
As I see the Recieved Buffer Errors at the system level, so even before

IIRC by default gmond will set buffer
size to 128kB which is insufficient if you are collecting lots of
metrics. These two commits change the behavior so that you can set
UDP receive buffer to higher as long as eg. net.core.rmem_max is
set
