            Description

            Here's the backtrace https://pastebin.com/TMAatVLb which is triggered when you got large number of smart groups and the underlying query wants to rebuild group_contact_cache in one go which is an expensive operation.

            So, we should optimize the underlying query that is the root cause for this issue
