Sorry about that Devendra . I _think_ the problem is the same one - OOM
Kills. This time it is with the backup software that runs in the morning.

The problem now is, we don't get any messages. Both dmesg and /var/log are
empty.

The script to restart things every hour is still in place. Also see
https://github.com/weidai11/cryptopp/issues/720 .

Yeah, but it will probably return until we get to the bottom of it. The
script will restart the MySQL service once an hour if needed so problems
will be transient.

I just updated the backup software called Duplicity. We were at duplicity
0.7.18, now we are at duplicity 0.7.18.2. Wait and see...
