Description
When JDBC connection is defined, it takes too long to start broker (from secs to minutes).
Similar issue was in AMQ6, but with starting the broker itself w/o JDBC.
To workaround this, one should use service rngd, which generates enough random numbers and results in a very quick connection to DB (via JDBC).
yum install rng-tools systemctl start rngd
Start broker now.
