[Nfd-dev] How to avoid Duplicate nonce generation on retrasnmitted interests

Hi All,

I am running NDN on top of NFD 0.6.2
On the consumer end, I have the same interface drop packets/connection with
NACK duplicate messages. On further investigation, I figured that some of
the interests with interrupted connections generate "same" nonce for same
interest packets (probably retransmitted) and whenever that happens, the
connection over NFD completely drops.
I came across this conversation thread
<https://redmine.named-data.net/issues/3888/> and found that this was a
design flaw that was corrected in v0.6 but I still came across this in 0.6.2

I was wondering if I could talk to someone regarding the issue and my
workaround it.

Regards,
Ishita Dasgupta
