FCRBWAIT

A recoverable file control request waits on resource type FCRBWAIT if file control has not completed the actions required to allow the processing of recoverable work. These actions include the rebuilding of non-RLS enqueues and restarting RLS access.

You do not see a task waiting on this resource type, because this wait occurs during CICS initialization.

Waiting on this resource can occur for files accessed in both RLS and non-RLS mode.
