Hello, is it unable to connect to 127.0.0.1:11211? If so, please check whether the site configuration is correct
1.Memcached is an upgraded version of Memcache
2.Has been processed, and the installation script updates the application store without update

zahari.amin

aaPanel_Kern currently, the site configuration is ok.
what is the best cache time or recommended setting for Website Speed to avoid Memcached crash?
before this, I put 600 sec and have now reduced it to 60 sec

FYI my website is in heavy traffic and using WordPress

Is cdn caching used?
Is the hit rate of Website Speed high? You can try to use a script to check whether the Memcached process exists. If not, start it again

zahari.amin

aaPanel_Kern the hit rate is around 30%-40%.... sometimes 50%
the problem is some times I need to restart/reload Memcached when the cache time for Website Speed is around 1200 -600 sec. after being reduced to 60 sec the problem is fine.

yes currently I'm using the Cloudflare CDN

Hello, observe whether the Load average of Memcached is normal? Observe before the next restart of Memcached.
