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
之后我不断收到这个错误：
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.

我已经删除了所有cron作业。但我仍然得到错误。请帮忙。 Thanx提前！
