Re: Increased I/O / Writes

Following https://www.keithf4.com/a-large-database-does-not-mean-large-shared_buffers/ 

and http://pgtune.leopard.in.ua/ and https://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server 

I changed the shared_buffer from 51GB to 35GB.

Now, I'm getting spikes every 15 minutes.

FATAL:  sorry, too many clients already

The change have been made 3 hours ago. 

- we rebooted the server as well

Might be the cache warming up again?
