Issue 2743: stream-events dropping events
Status:  New
Owner: ----
Reported by e...@demeterr.com, Jun 26, 2014
Affected Version:

version v2.9-rc1

What steps will reproduce the problem?
1. log ssh user@host gerrit 'stream-events' on multiple machines
2. diff logs

What is the expected output? What do you see instead?

Events are being dropped from one side or the other.

Please provide any additional information below.

We're running a gerrit instance in our Google Compute Engine project. We noticed that an in-house CI system (a node.js app) was sometimes missing build events. In our case running two instances of our CI system has detected 9 mismatches out of 300 events, initially we had thought this was related to running the CI instance in a separate project, but events have also been dropped from a CI instance running in the same project as gerrit. Nothing obvious is being logged from either gerrit or our CI system; events are missing but subsequent events come through cleanly (no garbled data, just a missing line of output).

Is there a way to turn on detailed logging for stream-events, or post-facto query which events gerrit thinks it has sent to which connections?
