Too many queue actions
An admin bulk queue operation was rate-limited. Message: “Too many queue actions. Try again shortly.”
Why this happens
Transfer-queue and mass-email queue tools allow a small number of bulk actions per staff user per minute (about 10 / 60s). This protects stuck-release / delete-all / retry-all style endpoints from accidental hammering. It is not the member upload file queue (ul2_max_batch_*).
Diagnose and fix
1. Wait about a minute, then retry the admin action once.
2. Avoid scripts that loop release/delete/restart against the same queue APIs.
3. Limits are code defaults — not a Users & limits toggle.
4. Member “too many files in batch” messages are different (see Max items / batch articles).
