I know there's an explanation on this error, but it really does not make much sense in our situation due to very low activity in our system at the moment, but we're getting this error every 2-3-4 minutes continuously for the past 20 minutes. There has no code change on this part of the API so please let me know if this is related to some bigger issue.

Full error along with stack trace:
