WHM Wordpress admin-ajax.php CPU 负载过高：错误“-1 ENOENT（没有此类文件或目录）”

致所有出色的专家：

我刚刚迁移到新的 VPS 服务器，并注意到 admin-ajax.php 在 WHM 中使用了非常高的 CPU%，当我跟踪该过程时，我可以看到大量访问错误，如图所示下面：

    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/dynamic-content/class-control-textarea.php", F_OK) = -1 ENOENT (No such file or directory)
    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/element/class-control-textarea.php", F_OK) = -1 ENOENT (No such file or directory)
    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/options/class-control-textarea.php", F_OK) = -1 ENOENT (No such file or directory)
    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/pro/class-control-textarea.php", F_OK) = -1 ENOENT (No such file or directory)
    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/regions/class-control-textarea.php", F_OK) = -1 ENOENT (No such file or directory)
    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/styling/class-control-textarea.php", F_OK) = -1 ENOENT (No such file or directory)
    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/templating/class-control-textarea.php", F_OK) = -1 ENOENT (No such file or directory)
    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/classic/builder/class-control-textarea.php", F_OK) = -1 ENOENT (No such file or directory)
    access("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/classic/controls/class-control-textarea.php", F_OK) = 0
    lstat("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/classic/controls/class-control-textarea.php", {st_mode=S_IFREG|0644, st_size=262, ...}) = 0
    open("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/classic/controls/class-control-textarea.php", O_RDONLY) = 5
    fstat(5, {st_mode=S_IFREG|0644, st_size=262, ...}) = 0
    read(5, "<?php\nclass Cornerstone_Control_"..., 262) = 262
    fcntl(3, F_SETLKW, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=1}) = 0
    fcntl(3, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=1}) = 0
    close(5)

如您所见，它在找到文件之前循环遍历整个目录然后关闭的过程。（这是在一个进程中，它在该进程中发生了大约 400 次）

我担心这是导致 CPU 过载的问题，并且它导致我的网页加载非常缓慢的前端和后端。

我也在升级我的服务器，但下面是我的服务器规格：

操作系统：Linux
CPU：2 核 Intel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz
内存：2GB
PHP 处理程序：suphp
CMS：Wordpress 多站点

在升级到 VPS 服务器之前，我从未遇到过此问题我担心这可能是与性能相关的问题。

我愿意接受任何建议，提前谢谢你们，请原谅我在 Linux 服务器上的经验不足

To all the awesome gurus out there:

I have just migrated to a new VPS server and noticed admin-ajax.php using up a very high amount of CPU% in WHM and when I traced the process I can see plenty of access error as shown below:

    open("/home/xxx/public_html/wp-content/plugins/cornerstone/includes/classes/classic/controls/class-control-textarea.php", O_RDONLY) = 5
    fstat(5, {st_mode=S_IFREG|0644, st_size=262, ...}) = 0
    read(5, "<?php\nclass Cornerstone_Control_"..., 262) = 262
    fcntl(3, F_SETLKW, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=1}) = 0
    fcntl(3, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=1}) = 0
    close(5)

As you can see, it cycles through a whole directory before finding the file and then closing the process. (this is in a single process where it happens about 400 times in that one process)

I'm concerned that this is the issue that is causing the CPU overload, and it's causing my webpage to load really slowly frontend and backend.

I am also in the midst of upgrading my server but here's my server spec below:
