hi,
this warning occurs while running
reco_trf.py ami=c756
this is a tag we have defined for reconstruction of files where the trigger was rerun - it should just connect to the database triggerdebr, obtain the keys and run full reconstruction. if there is indeed a problem with the reconstruction then this is very serious - we use such jobs to validate all changes to the online trigger configuration.

please let me know if further information is required.

cheers,
stewart
