我正在从我的 cpanel 添加多个 cron 作业。大约 10 分钟后，我收到了一封电子邮件
execl: couldn't exec `/bin/sh'
execl: Resource temporarily unavailable
之后，我不断收到此错误：
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@********.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
Apache Server at www.******.com Port 80
我已经删除了所有的 cron 作业。但我仍然收到错误消息。请帮忙。提前谢谢！
