Our database is spiking at 99% I/O at random times. There are not some "super" queries that are running in these intervals. We are running a vp on digitalocean with 16 GB Ram, 8 CoreProcessor and 160GB SSD Disk. Out databse takes 1BG of data. We suspect there is something wrong with our config- We have 13 GB free memory. Does annybody know whats wring? Do i need to provide more info? Is there annything i should be logging?
