I am new to Redis and Magento both, so please ignore any misleading/non-correct terms,

I am working on Magento V1.9.2.4 configured Redis V3.0.7 with Mage_Cache_Backend_Redis, we have OS REDHAT 7.x installed on the server.

The site on production goes down(i.e. loads without CSS and images) very frequently and after restarting Redis and its services by the below command, site loads normally

sudo systemctl restart redis-sentinel redis-obj redis-fpc redis-ses

I had a look over the server error.logs, exception.logs do not found any suspicious log entry anywhere

I had a look into Redis configuration on /var/run/redis/redis-fpc.conf and Redis default configuration on OS it's all the same except below points:-

  1. Currently, the Redis version is 5.x and I have Redis version installed is 3.0.7
  2. Default Redis: databases 16 and I have Redis conf on the server is databases 2
  3. There was a suspicious warning in redis-obj.log file

20980:M 23 Aug 07:05:01.887 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

But that warning is also removed with the help of service providers support,

I want any possible lead in order to resolve this(website goes down) issue for my searching,

Now I am like blindly thinking/looking into the configuration files for the Issue,

It'll be a very great help from my side if anyone/community who knows or assumes the possible reason for this issue I'm struggling with,

Many many thanks in advance.
