Worker threads that are waiting for a work response get interrupted if they are still going after the execution has completed (See RedisShardBackplane.pollExecution and ShardWorkerContext.resumePoller and Executor.runInterruptible). This is happening to us often. Assuming the problem is in buildfarm, and not our rules, it may be that the execution writes its entire response and completes within the span of the Thread.sleep(10) call, and then the poller sees that the execution is complete and interrupts the thread before it gets the chance to check the output stream again. This seems a bit far-fetched, but it's the only explanation I came up with. If it is what is actually happening, we can avoid failure by ignoring the interrupt and reading the available response when we are interrupted with a response available.
