Because the read and write operations of the .info file cannot guarantee atomicity, and there are many conditions that can trigger this problem, the 0x98 byte is an invalid UTF-8 start byte.

The writing process of the original xmlSaveFormatFileEnc() has been modified to complete the atomic write and data integrity protection mechanism, in order to prevent .info / XML files from being damaged due to non-atomic writes or illegal UTF-8 bytes.






Main changes explanation:


    

  1. Added atomic write process
    2. 

  2. Completed data durability guarantee
    3. 

  3. Added UTF-8 validation
    4. 

  4. Error handling and cleanup
    5. 

  5. Header dependency adjustments (compilation impact)
    6. 

Create VA & see /var/log/avxd.log:


save_xml_atomic: OK: valid UTF-8





Array CLI:


AN(config)#sh sys res
