Upgrade hub probe to 7.x from 5.82 or below.
hub probe 5.82 or below was using old format queue files which name start from q_<queue name>.sds in <Install Dir>\hub\q\ directory.
When there is old format queue file, hub 7.x creates new format queue file without checking existing one. Therefore, new 0.sds will be created and old queue messages are deleted.
For example, suppose there are following files.
<Install Dir>\hub\q\q_nas.sds ========> This is old format file
<Install Dir>\hub\q\nas\3.sds ========> This is new format file. And, current file sequence is 3.
After recycle of hub probe, the new format file is reset to 0.
After upgrade hub probe to 7.x, please make sure there is no old format file q_<queue name>.sds in <Install Dir>\hub\q\ directory.
To avoid this, please follow instruction below.
1. Stop Nimbus
2. delete q_<queue name>.sds from <Install Dir>\hub\q\
3. Start Nimbus
