If this is Ubuntu, I would check for "unattended upgrades" package: https://documentation.ubuntu.com/server/how-to/software/automatic-updates/ as this service WILL unexpectedly restart services.  Generally speaking, unattended upgrades are a very bad idea because things may break during an update and a human needs to be in attendance so that they might be fixed in a timely fashion (actually, upgrades should first be tested in a lab environment if you want to be really safe).
