If you have issues with the databases that support the
console, make sure that the PostgreSQL database is not too
large or using too much memory, that you don't have port conflicts, and that
puppet apply is configured correctly.
PostgreSQL is taking up too much space
autovacuum=on setting prevents the database
from growing too large and unwieldy. Routine vacuuming is turned on by default.

PostgreSQL buffer memory causes installation to fail
When installing PE on machines with large amounts of RAM, the PostgreSQL database might use more shared buffer memory than is available.
/var/log/pe-postgresql/pgstartup.logshows the error:
FATAL: could not create shared memory segment: No space left on device DETAIL: Failed system call was shmget(key=5432001, size=34427584512,03600).
On the primary server, set the
shmmaxkernel setting to approximately 50% of the total RAM.
shmallkernel setting to the quotient of the new
shmmaxsetting divided by the page size. You can confirm page size by running
Set the new kernel settings:
sysctl -w kernel.shmmax=<your shmmax calculation> sysctl -w kernel.shmall=<your shmall calculation>
The default port for PuppetDB conflicts with another service
By default, PuppetDB communicates over port 8081. In some cases, this might conflict with existing services, for example McAfee ePolicy Orchestrator.

puppet apply to PuppetDB
If Puppet apply is configured incorrectly, for example

storeconfigs = true in both the main and
primary server sections,
