Hello,

In the past week or so, the httpd service of server has gone randomly, and it does not start automatically .
I get the email :
1586800984490.png
1586800995497.png


CSF is disabled. I searched for a solution, and the only thing that i came across is to run this command to check Semaphore limit:

Bash:
# cat /proc/sys/kernel/sem
32000    1024000000    500    32000
I think the number is fine from what i saw, also the server is on very little load ~100 concurrent visitors.
Here is the logs of /usr/local/cpanel/logs/error_log at the same time when i got the notification.

Code:
==> cpsrvd 11.86.0.18 started

Hello,

Have you checked the actually Apache error logs for what the reason for the shut down is? You can find them at /etc/apache2/logs/error_log
Hello,

I have checked the apache logs, but it's seems i did not find anything usual, also there is no error logs around the same time when i got the notifications.
Generally, what are some red flags that i should pay attention to in apache logs?
And what else i can check to pin point the root of my issue?

Thank you for your replay.

Hello,


The only locations that would list this during the time of the error would be the system logs at /var/log/messages or the apache error logs. If there was an apache error it would be noted in the log file there. And if there was a system issue like the process was killed or the system ran out of memory it would be listed in system logs.
