We have recently changed some of our code to include additional call to
SourceLookup.extractValue(path) in fetch stage. Soon after, we have started
experiencing some issues with search stability (with some of our searches
failing to finish, others taking very long).
I can see search lookup queue getting filled up (to 1000) and I can see the
following spamming the logs:

There is also a long GC running at the same time, not sure if it might be
the cause or the effect.
Is it at all possible that this might have been caused by a call to
SourceLookup.extractValue() assuming the field that is extracted was not
specified in the query?
