I've had a cpanel server running on an eight core VPS for many years. I am migrating to a new server in a different data center due to server stability issues (data center keeps having "fires" and crap)...
The new server according to its specs is slightly more powerful than the old setup. 8 x Intel(R) Xeon(R) CPU E3-1270 V2 @ 3.50GHz and 8GB of memory.
The problem is that I have noticed on the new server that when the server load indicator spikes above 2.5 or 3 then suddenly I start getting notifications from my monitoring site that several of my websites are down. Sure enough, I check, and the site just sits there and sometimes takes several minutes to load, usually once the load has dropped.
This happened yesterday when I was using the transfer tool to move a large 15gb account over to the new server. Then it also happened today for no apparent reason that I could tell. Another time it apparently happened when it was running the overnight backups.
Both servers are running the same version of cpanel and Centos. Old server is running MariaDB 10.2, new one is running what was installed when the server was created, MySQL 5.7 I remember many years ago doing some tweaking to my.conf but have not done anything like that on the new server. Not sure if that is even a possible cause but thought I would mention it.
Any idea what things I should look at on the new server to fix this problem? Thank you in advance!
