DBBADFREEBLKCTR, Database xxxx free blocks counter in file header: oooo appears incorrect; should be nnnn. Auto-corrected.
Run Time Warning: This indicates that during a file extension, because they differed, GT.M adjusted the free blocks counter (oooo) in the file header to agree with free blocks indicated by the master map (nnnn). Because this may indicate a master bitmap integrity error (DBMBPINCFL), check the next MUPIP INTEG carefully.
Action: Run MUPIP INTEG; if it reports a DBMBPINCFL integrity error, use DSE to correct it, and to increase the file header free blocks counter by the amount GT.M reduced it in the DBBADFREEBLKCTR message. Run an additional INTEG to confirm the corrections.
