This trap is sent when an overrun occurs when writing to the file. If multiple consecutive overruns occur, this trap is only sent once, upon the occurrence of the first overrun. Once sent, this trap will not be sent again until a write operation has been successfully performed, and a period of 15 minutes has elapsed without any additional overruns or write operation failures. This trap is not sent if the most recent write operation failed or if a write operation failed within the preceding 15 minute period. (I.e. This trap is sent only when the status of the port is 'No recent errors.) The port number of the NFS port on which the failure occurred is contained in fscSerialTrapObjectPortNumber. The status of the NFS port on which the error occurred is contained in fscSerialTrapObjectNFSPortErrStatus. (This is the status of the port at the time that the Trap was generated.) The fscSerialTrapObjectNFSPriErrorReason specifies the main reason of failure and can have any value defined in NFSErrorReasonEnum. The fscSerialTrapObjectNFSSecErrorReason specifies the secondary reason of failure and can have any value defined in NFSErrorReasonEnum or if there is no detailed reason then the value will be zero.
