There are multiple reasons for TMSINIT to produce this abend.
1. The audit file is allocated but not formatted.
2. The audit file was allocated and formatted but has a short block of data at the end of the file. This could have been caused by moving the file using IEBGENER and changing the BLOCKSIZE.
Allocated and formatted a new audit file using TMSFORMT. TMSFORMT will make sure that the last block on the file is a full block of data
If you need to move the Audit file do not change the blocksize. If you want to change the blocksize use TMSFORMT and format a new file on the DASD volume where you want it to reside.
