+# This temporary workaround for issue #2656.
+# The root cause is an issue in Rails: https://github.com/rails/rails/issues/33600
+# It disables database connnection reaping by setting `reaping_frequency` to 0 for each environment in the config/database.yml file.
+# It restores the DB connection reaping behavior Rails > 5.2 had.
+# It was proposed in a comment on the Rails issue: https://github.com/rails/rails/issues/33600#issuecomment-415395901
+# It was confirmed by @matthewd (a Rails core maintainer) in another comment: https://github.com/rails/rails/issues/33600#issuecomment-415400522
