Bug #14716
Updated by nobu (Nobuyoshi Nakada) over 6 years ago
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 -- : /usr/lib/ruby/2.5.0/securerandom.rb:99:in `urandom' E, [2018-04-27T04:55:08.741898 #16550] ERROR -- : /usr/lib/ruby/2.5.0/securerandom.rb:99:in `gen_random_urandom' E, [2018-04-27T04:55:08.741932 #16550] ERROR -- : /usr/lib/ruby/2.5.0/securerandom.rb:129:in `random_bytes' E, [2018-04-27T04:55:08.741965 #16550] ERROR -- : /usr/lib/ruby/2.5.0/securerandom.rb:219:in `uuid' E, [2018-04-27T04:55:08.741997 #16550] ERROR -- : /usr/share/nginx/frontend/app/utilities/log.rb:74:in `create_session_info' E, [2018-04-27T04:55:08.742036 #16550] ERROR -- : /usr/share/nginx/frontend/app/utilities/log.rb:11:in `context' ``` 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?
