I manage multiple website with infinitewp, maybe infinitewp is the problem. All the plugins I use are very popular so I don't think that's the problem, because other people should have the same problem. Which plugins do you use?

edit:

I don't no why but the problem is solved.

recently i have this problem too..
# 1GB ram VPS, CentOS 6.7 64bit
# Wordpress avg 2k visitor & 10k page view (increasing)
# MySQL Community 5.5.46

but after i disabled (suspend) MySQL port at firewall menu on VestaCP, the problem is decreasing alot.
but sometimes crash too, maybe around once/twice per month.

for me, enabled "I'm Under Attack" in CloudFlare doesn't solve the real issue, because i'm not using CloudFlare.
now my mysql database crash often, because increasing visitor/pageviews i think.
now i try to play with httpd configuration, to limit memory usage.
i still learning how to optimize my vps, especially httpd/mysql configuration.

note:
# i'm still not upgrade my vps (1GB RAM), only 1 web on this vps
