Would like to know what will happen to missing transaction as revealed by the curl command.

My node (iri version 1.4.1.4 in sync) now has about 10 and sort of slowing creeping up by the hour.

curl http://localhost:14265 -X POST -H 'Content-Type: application/json' -H 'X-IOTA-API-Version: 1.4' -d '{"command": "getMissingTransactions"}' | jq
