The ASM already has 64 ASM disk groups that are working fine.
Creating 65th asm diskgroup is also successful, and the 65th diskgroup is mounted without an error.
However, when database tries to create a tablespace using the 65th asm diskgroup, the create tablespace command fails.
Two different errors are observed when CREATE TABLESPACE is issued
1) In one occasion, the following error is reported
