On Exadata cellnodes, the RS-7445 error can be received due to the inability to send heartbeat under overload. This error appears in versions 11.2.2.4.0 and 11.2.3.2.1 of the Oracle Exadata Storage Server software.

As a result of the error, the CELLSRV service is restarted by RS. When Cellnode alert.log is examined, errors will be seen as below.
