書き込みに使う一時的なOSリソースが足らない、という感じですね。
(このマシン側か、書き込み先のマシン側は不明)
書き込み先マシン(or NAS)の情報をなるべく詳しく教えてもらえますか?

OS標準のコピーですと転送速度は少し遅いですが転送出来ます。

なるほど。
I/O単位は 1MB と思いますが、非同期I/O発行数20をもう少し小さくして、動作確認してみてください。
20 → 8 に減らして動作確認し、それでもダメなら 4 → 2 → 1 と減らして確認してみて下さい。

ご報告ありがとうございます。
とりあえずは、18以下で動かしていただければと思います。
この数字はWANなどの遅延の大きい環境で特に効果を発揮するパラメータなので、
LAN内であれば 10 でもさほど速度低下はないはずで、若干マージンを見て 10 あたりが良いかも?
ともあれ、書き込み側&ファイル末尾近くで ERROR_NO_SYSTEM_RESOURCES (1450) が発生するという
というのは初めての報告でした。他環境でも類似報告が多いようであれば対策を検討しておきます。
