Wordpress CentminMod clearing the transients automatically everyday

Hi,
recently I've installed wordpress in one of my subdomain using the centmin.sh menu and by default it added cache enabler, cdn enabler, scuri etc. plugin. After installing WordPress I've deleted these plugins of my site and started using the redis + redis nginx combination in my subdomain like my main site.

Now everything is working fine but there is just one issue that is highly bothering me. In this new install I can see that somehow all the transients within WordPress gets deleted everyday and this is creating a problem for me as many plugin uses transients to hold key data.

---

Is there any way I can delete this auto transient deletion from my wp install?

 

Its not about everything. But I just don't understand whats clearing the transients everyday...

 

I have tried disabling the redis object cache plugin for one day and it still removing all transients everyday...

Now the problem is that different transient has different expiration time, so if it deletes all transients everyday, it just doesnt make any sense.

 

I also see these following define statements in my wp-config file:

Code:

define('WP_CACHE_KEY_SALT', md5( DB_NAME . $table_prefix . __FILE__ ) );
define('WP_REDIS_MAXTTL', 28800);
define('WP_REDIS_DATABASE', 6);

should I comment them out?
