> Key: GEODE-5513
> URL: https://issues.apache.org/jira/browse/GEODE-5513
> Project: Geode
> Issue Type: Bug
> Components: client queues
> Affects Versions: 1.6.0
> Reporter: Kenneth Howe

> Priority: Major
> Labels: pull-request-available
> Fix For: 1.7.0

> Time Spent: 20m
> Remaining Estimate: 0h

> Here is the scenario:
> Consider two servers and client:
> - Server1 hosting the primary bucket
> - Server2 hosting secondary bucket and also primary queue for the Client2
> - Client1 Doing remove operation
> - Client2 doing register interest
> - The Client1 starts remove-all operation
> - At the same time Client2 is registering interest
> - Server1 receives the remove-all operation processes it, and sends the
> adjunct message to the Server2 (Its still not yet received the interest info
> from server1)
> - While the remove-all to server2 in flight
> - Server2 sends interest profile info to Server1 for client2; and then
> Server2 (as it is hosting the primary queue) starts building the initial
> image snapshot for the interest. When building initial image for PR
> preference is given to collect data from local node. During this time the
> removal message is still in flight and hasn't applied on Server2. The initial
> image for interest registration calculates the snapshot from local data, and
> sends it to client, missing the remove-all op.
> This could happen with non-bulk ops; but it gets worse with bulk ops as the
> time taken to replicate the bulk ops will take more time.
> The solution is to build the initial register interest response by getting
> the data from primary bucket. This will add little overhead in building the
> interest response; but considering that most or always the register response
> will involve remote node, this may be negligible.
> Clients registering interest in a region
