ERROR_CLUSTERLOG_RECORD_EXCEEDS_MAXSIZE

ERROR_CLUSTERLOG_RECORD_EXCEEDS_MAXSIZE means a single cluster-log record was too large to be written. The condition can identify an unexpectedly large diagnostic payload or a component that is producing excessive log data.

What to check

Collect a fresh Cluster.log and identify the component that emits the oversized record.
Check recent resource DLL, provider, backup, or management changes that might have introduced unusually large status data.
Review the preceding resource and cluster service events; the record-size error is usually secondary to another operation.
