This is neither `free -m` output or `uptime` output. Buffers and cache
values are important, thus the original request. At least I don't have
time to debug issues when I don't get the *full* details I ask for.
`df -h` would be good too, but I'm not going to waste my time here
unless you offer some help and at least attempt to look into this on
your own.

With a load average between 1 and 5, I'm guessing you have several
tasks high on disk I/O. I would recommend digging into `vmstat` and
`iotop -o` output and doing debugging of your own.
