Raul Gutierrez Segales commented on ZOOKEEPER-2102:
---------------------------------------------------
Oops, this bug isn't so — I had an error in zab-dump which was printing the
wrong message types! So all is good, sorry for the false alarm [~shralex]!
Here's a snippet of traffic with the bug fixed in zab-dump:
{noformat}
$ grep type log | sort | uniq -c
2793 type=ack,
3860 type=commit,
27087 type=inform,
3584 type=ping,
3648 type=proposal,
769 type=request,
2826 type=revalidate,
{noformat}
Which is more or less what we'd expect — no non-expected messages!

> Using zab-dump (https://github.com/twitter/zktraffic/pull/11), I am seeing
> this in a prod cluster running 3.5.0 + patches:
> {noformat}
> QuorumPacket(
> timestamp=18:45:35:962873,
> src=10.0.1.1:2889,
> type=commitandactivate,
> zxid=292104572694,
> length=114
> )
> QuorumPacket(
> timestamp=18:45:35:962876,
> src=10.0.1.1:2889,
> type=commitandactivate,
> zxid=292104572694,

> QuorumPacket(

> src=10.0.1.1:2889,
> type=commitandactivate,
> zxid=292104572694,
> length=114
> )
> ....
> {noformat}
> From a ~5min dump, I see ~80k QuorumPackets of which ~50k are
> commitandactivate packets! Sounds like some sort of loop.
> Any ideas [~shralex]?
