That's what the logs are for... To source out problems so you can fix them.

From the log portion you posted, there are no errors. It looks like the server is being shut down and then restarted. What type of web sites are you hosting? (Wordpress?)

What do your logs say. You only posted a small part of the apache log. What about the syslog? Check the entries in syslog that are during the same time as the apache log. Also check the auth log for the same time frame.

what you are seeing is the full , this file was created only on yesterday and day before yesterday on separate logs containing same errors.

I checked the server uptime, it doesn't seems to have shutdown inbetween. is there a chance only the httpd service is getting restarted often on any triggers.

But after 18 50 yesterday shown on the log there is no any update on the file.

I have hosted php website on the server ....


I have attached sentora log along this were u can see someone is trying to access

It looks like somebody is attacking your server. You need to set up fail2ban and firewall rules to block/ban repeated hits.
There are also a lot of file not found errors.

@[Me.B], any other suggestions?

Likely some one is trying to brute force sentora panel.

The solution would be to ban the offending IP. Fail to ban won't protect the panel currently as you will need to add a manual rule for it.

Check the logs and ban them using iptables. Alternative solution try to use cloudflare, it may help over those automated attacks.

Yesterday I blocked some ips...today its coming from different ips....

how can I use cloudfare ? or is there any way that I can permit only my country ip to access the server ?
