The solution is to figure how to break that record up into many small records. You have probably memory leak in your server. More likely there is a DoS attack or just some FSM queue overload.

Other more drastic options you might consider: Temporarily install more more RAM.

The match_object methods may return a huge number of records, and all those records have to be sent from the table process to your process, doubling the amount of memory required. You should also consider adding more swap and tweaking the overcommit ratio. It may even work partially, given certain error situations, causing database inconsistency.
