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

ORA-15001: diskgroup "TEST_STORAGE" does not exist or is not mounted
ORA-15064: communication failure with ASM instance

2) In another occasion, ora-600 is reported

ORA-00600: internal error code, arguments: [kfnSlaveGroupUse], [KFGN_MAX],
