Hi,

We recently upgraded from ruby 2.3.6 to 2.5.1.
We use SecureRandom.uuid to generate a random number for our session.
Post the upgrade we have been getting the following error intermittently

```
app error: failed to get urandom (RuntimeError)
E, [2018-04-27T04:55:08.741859 #16550] ERROR -- : \

We understand that there was a change in ruby 2.5.1 where we now look at OS sources \
as the first point of contact to generate random numbers as opposed to OpenSSL. Any \
idea why this could be happening?
