مشکل با down شدن vps cpanel در ساعت 4 صبح و 4 عصر

[User vmware]

سلام در این ساعت ها سرور down میشه و این ایمیل ها بهم میاد

این وی پی اس یه یوزر داره که دانلود زیاد ازش میکنن به نظرتون چی کار کنم الا ن که چک کردم نه سی پی یو مصرف میکنه نه رم اما اینطوری شده بود
4 صبح ها هم که نمیدونم چرا اینطوری میشه

لاین سرور هم 1 گیگ هست به نظرتون لایسنس nginx بگیرم براش؟
ایپی های وی پی اس های دیگه سرور رو هم بلاک میکنه به این صورت
