I had a similar issue with a deleted dataset.
Turned out I had to go back 3 weeks to find the job that had deleted it. I
knew it was a nonvsam data set so I just scanned the 14, 15, 17, 18 records.
The 60 records are needed if it is VSAM.
What happened was a batch job had failed to code the JCL properly. Had a blank
after the data set name and before the DISP parm.
//STEPLIB DD DSN=prod.data.set.name ,DISP=SHR
When this job ended the data set will be deleted as soon as the other enqueues
against it were gone. This took 3 weeks (this was an IMS RESLIB data set).
Next thing we knew, IMS would not come up because this file had been deleted.
So, have you gone far enough back in the SMF data to find the culprit.

Looks like an excellent argument for RACF protection. IACC of READ might
be most appropriate here.
I HIGHLY recommend DAF, from the CBT site, to find the culprit.
