Description of problem:
Occassionaly httpd will refuse to start after reseting the vmdb.  This is causing a lot of my performance tests which require reseting the database to a clean state to run correctly.



Version-Release number of selected component (if applicable):
5.5 appliances

How reproducible:
Intermittent, sometimes resets will go smooth 10-20 of them and then once httpd refuses to start it requires an entire reboot to allow it to start again.

Steps to Reproduce:
systemctl stop evmserverd
systemctl restart rh-postgresql94-postgresql
vmdb
bin/rake evm:dbsync:local_uninstall
DISABLE_DATABASE_ENVIRONMENT_CHECK=1 bin/rake evm:db:reset
bin/rake db:seed
systemctl start evmserverd

* evmserverd starts, httpd just refuses to start

Actual results:
# systemctl start httpd
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

# systemctl status httpd
