Attached are monthly graphs and htop stats apache server status doesn't hint on clear winner, there are processes from all sites. It's 50-60 WP sites with low traffic on the 2cpu, 2gb ram, 6gb swap SSD VPS wp-login.php anx xmlrpc.php are blocked server wide I'm not very experienced but at...

Do you guys think adding a cron job to restart apache once per day or so is viable solution at all? I mean it feels more like masking the problem instead of fixing it but at this point i'm out of options? as a side note vestacp reports the LoadAverage: 3.27 with 2 days uptime uptime in...

Nah, it will break too much stuff. Those haven't been updated for a while and have plenty of plug-ins. It will be a nightmare. and we are talking about 100 sites here. And still it will be a shot in the dark. I would prefer to identify the problem and fix just that. Not break 100 other things :)

No, those WPs haven't been updated for  a while.

well mostly WP sites they were causing problems before but before i narrowed it down to wp-login.php and xmlrpc.php whcih are now server wide blocked in the nginx template before they were filling up the processes in extended status and it was obvious now i really can't narrow it down before...

So, I have to look for the reasons for the CPU usage by apache somewhere else? But if none of the other apache slots is anything significant what else it might be?

I'm struggling to keep all of them updated so was wondering what the others do. How often you apt-get update and do you always backup before doing so? What are generally considered good practices to keep them as updaded as possible without overkilling it? Have you ever have the update break...

My extended server status has like 100 of these right now Srv PID Acc M CPU SS Req Conn Child Slot Client VHost Request 0-0 - 0/0/474 . 1.40 12760 0 0.0 0.00 1.98 EDI.TED.IP.XX 127.0.1.1 OPTIONS * HTTP/1.0 Short google on OPTIONS * HTTP/1.0 shows many people having those (but with...

yeah it's VPS probably KVM tcpdump outputs this, like a ton per second 17:31:59.486534 IP6 2001:19f0:5c00:8000::1 > ff02::1:ff92:6af9: ICMP6, neighbor solicitation, who has 2001:19f0:5c00:94c1:6cd7:94f:7a92:6af9, length 32 17:31:59.486637 IP6 2001:19f0:5c00:8000::1 > ff02::1:ff00:64: ICMP6...

For the last few days  I have 2 to 4 mbits of incoming traffic hitting a fresh VPS with couple of sites on it that don't get any traffic at all. I can see via the control panel (vestaCP) that none of them is getting any traffic. iftop doesn't show any significant traffic to anything top...

yes I had problems with wp-login before and now it was xmlrpc and now both are blocked at nginx level for the whole server how does one check the mysql processes I just learned how to check the apache ones, lol :)

well apache status was showing like 200 processes and 90% of them occupied by that same file from the different sites probably someone taking advantage of my server to attack others thank you! I'll try that code later you guys are great

This command works like magic! Thank you so much for it. That was exactly the smart way I needed! :) Yes, I just confirmed that I've fixed it. Well it wasn't just one site, it was all of them! I had the xmlrpc.php file of all WP sites causing the load. It would take an apache worker and hang...

well that's the default vestacp template with just this part added location / { location ~ wp-login.php { allow 127.0.0.1; deny all; } so you sure it is that bad? anything constructive to say about how to actually do it?
