<<<<1. You have 8 GB RAM. You have set innodb_buffer_pool_size to 23 GB, It should be about 25% of that.

At the terminal prompt run ...

free -m

and post the results. I think that will show there is a lot of swapping. If that's so, you need better settings and perhaps more RAM. >>>>>>>>

Sir,
I am not DB guy, could you please help me what are the best settings to avoid all my issues. my only request is as you said, i will try to tune my queries , as you said i will avoid left joins but as per my business needs to i should use left joins.

2. Inefficient queries are clogging your server. They need to be optimised. Turn on the slow query log specifying queries that run more than a few seconds, optimise the queries that it reports. >>>>>>>>

Inefficient queries means, because of left joins my server is clogging?.
