Increasing the max # of hosts that can be built at the same time?

I am running an instance of foreman in a VM with the following
characteristics:

vmxnet3 driver running on a dedicated 10g card (main vmware card that is)
32GB of memory
4 cores
Centos 6.7

I haven't done anything yet, but when I try to boot more than 3 machines
for provisioning, they choke. Is there any way to increase the max # of
simultaneous hosts being provisioned?

Hey,

can you try to increase Passenger limits in
/etc/httpd/conf.d/05-foreman-ssl.conf ? By default passenger is set to
autoscale up to six processes, you can increase this but watch free RAM!
These guys can take some memory with ease…

PassengerMinInstances 6
PassengerStartTimeout 900
PassengerMaxPreloaderIdleTime 0
PassengerMaxRequests 10000

In /etc/httpd/conf.d/passenger.conf configure maximum limits:

<IfModule mod_passenger.c>
PassengerRoot …
PassengerRuby …
PassengerMaxPoolSize 24
PassengerMaxRequestQueueSize 200
PassengerStatThrottleRate 120
</IfModule>

Consult Passenger docs for these values, the above is medium sized
server.
