We traced this problem to a known bug, JIRA DB HDFFV-9281, "Attribute creation index can't be incremented", previously reported by Andrey Paramonov:
I believe the root cause is the management of the per-variable maximum attribute creation index within HDF5. This is a 16-bit counter with maximum value 65535. Careless usage patterns within client applications can easily saturate the counter. In particular, repeated delete/recreate cycles on the same attribute name will ramp up the counter. That is what happened in our own use case below.
Here is a related netcdf-C Github issue with excellent analysis by Constantine Khroulev:
I think you can close the newer JIRA ticket HDFFV-10026 and mark it duplicate, or merge it with the previous JIRA DB HDFFV-9281.
We look forward to some kind of fix at the NetCDF or HDF5 level. Thank you for looking into this.
