is this a bug? shouldn't we be returning an error.

I think that explains it then - the server is probably dropping the new
(3.3.0) "getChildren" message (xid 7) as it (3.2.2 server) doesn't know
about that message type. Then the server responds to the client for a
subsequent operation (xid 8), and at that point the client notices that
getChildren (xid 7) got lost.

Oh, OK. When I get a moment I'll restart the 3.2.2 and post logs,

Yes, we're calling getChildren with the callback.

I'm still interested though... Are you using the new "getChildren"
api that was added to the client in 3.3.0? (it provides a Stat
object on return, the old getChildren did not). While we don't
officially support 3.3.0 client with 3.2.2 server (we do support
the other way around), there shouldn't be they type of problem with
this configuration as you describe. I'd still be interested for you
to create that jira.

I thought I was running 3.3.0 server, but was running 3.2.2
server with 3.3.0 client. I upgraded the server and now all works
again. Sorry to trouble y'all.

Hi Jordan, you've seen this once or frequently? (having the
server + client logs will help alot)

Sure - if you think it's a bug.

We were using Zookeeper without issue. I then refactored a
bunch of code and this new behavior started. I'm starting ZK
using "zkServer start" and haven't made any changes to the
code at all.

I'll get the logs together and post a JIRA.

Hi Jordan, Can you create a jira for this? And attach all
the server logs and client logs related to this timeline?
How did you start up the servers? Is there some changes you
might have made accidentatlly to the servers?

Thanks mahadev

We've just started seeing an odd error and are having
trouble determining the cause. "Xid out of order. Got 8
expected 7" Any hints on what can cause this? Any ideas
on how to debug?

We're using ZK 3.3.0. The error occurs in line 781
