BlueImp jQuery文件上傳和ModSecurity錯誤

Question

我從使用BlueImp的批量上傳中遇到間歇性錯誤。 我在其他LAMP機器上使用了相同的代碼/配置，沒有問題。

在一個小時的過程中，我使用BlueImp進行的批量工作上傳從接受我扔給它的任何文件到每次上傳均引發ModSecurity錯誤。 我已經聯系主機，以查看我的IP是否被標記或具有這種性質。

鑒於涉及到的BlueImp代碼非常龐大，因此我不會發布所有代碼，而只是從UploadHandler.php中進行初始化。

有沒有人遇到過這個問題，或者是否有人有建議重新調試此步驟的第一步？

錯誤：

在這種情況下，事實證明我的主機在我的VPS之外具有我的VPS的/ tmp，並且已滿。
