"status.cc:114] Query id 0:0 not found" every second in Impalad logs

[Mostafa Mokhtar]

Recently I started seeing what appears to be an error message followed by a
broken stack that get printed every second, the message keeps getting
printed even when there is no query running.

This appears to be coming from ImpalaServer::GetRuntimeProfileStr
<https://github.com/apache/incubator-impala/blob/master/be/src/service/impala-server.cc#L589>
or ImpalaServer::GetExecSummary
<https://github.com/apache/incubator-impala/blob/master/be/src/service/impala-server.cc#L630>

Anyone knows what is going on?
