Hello,

I have an issue with Nginx cache loader since I’m using it, from 1.0.0  
to 1.0.4. It always exit one minute after Nginx starts as you can see in  
the following error log :

Anyone have an idea why the cache loader process is exiting ?

Thanks,

Most likely reason it finished loading cache. Everything else  
will be done by cache manager and worker processes.

Thanks for the quick reply Maxim. I thought the cache loader should be  
always running.
