I have a wordpress multisite website. On daily basis, the website is getting down for a interval of 6 to 10 minutes almost every day. I noticed in newrelic dashboard,that every 6 hours the website is experiencing peak load.
Not sure, what is causing the problem. The site has SSL Certificate and works under CDN. Am using the below list of plugins:
easy-social-share-buttons3 all-in-one-seo-pack broken-link-checker contact-form-7 image-slider-widget quick-pagepost-redirect-plugin forms-3rdparty-integration aryo-activity-log simple-301-redirects threewp-broadcast simple-custom-post-order seo-image members seo-optimized-images ip2location-redirection facebook-thumb-fixer unconfirmed
If anyone could suggest or think what might be causing the problem, it would be really helpful.
