This indicates you are using BDAM or VSAM master files and the member has hit the 255 physical block limit. You have several immediate and long-term solutions to address this concern:
- Delete one or two of the oldest archive levels. (This is only temporary and the problem will reoccur when updates are made again.)
- Increase the blocksize of the master file. (This is a more permanent solution.)
- Convert the master file to Wide Record Master File format. (This is a permanent solution as Wide Record Master File members do not have a 255 physical block limit.)
Refer to TEC448242 document on how to increase the block size for your Librarian Master File.
