Can anyone explain exactly what situations cause this message? Has the CRON process been killed or not? What should I do in response to this message? I am not familiar with Linux.
Remote server: Centos with CPanel and WHM
Local email client: Thunderbird on Windows 8
I deleted many small parts of the message because your forum software complains that there are URLs in it when there are no URLs in it.

Cannot understand lfd error message from system
Re: Cannot understand lfd error message from system
It's because you have Process tracking enabled. Check out point number eight in csf readne.

Re: Cannot understand lfd error message from system
martinp, thanks for the pointer. My guess is that my PHP tool that I run under cron sometimes hangs because the remote server is hanging while attempting to deliver the desired file. My further guess is that this happens because the Internet is so complex that sometimes it has to keep trying, instead of hitting a shorter (better) timeout than 70 seconds. If this is so, then there is just nothing that can be done about this: the cost of an occasional hang of 70 seconds and an email to me is necessary if I want to have the exploit protection offered by lfd.
Can anyone else here confirm that this analysis is correct? Thanks.
