Jira issue: CRDB-65708

Start with pkg/storage/pebble_batch.go and pkg/kv/kvserver/logstore/sync_waiter.go, then follow the reported write path into the Pebble syncing_file.go and log_writer.go references. Determine why the allocation failure reaches SyncWait as a panic and identify a reproducible test or diagnostic path; done requires a confirmed cause and an agreed fix scope.
