Description
I don't have any real information other then I was seeing OOMs and checked passenger:

Do you have any plugins installed (Administer > About, or foreman-rake plugin:list)? Try to reproduce it on a regular Foreman installation if you do.
I can't really suggest anything else without some information about how to reproduce it.
It's possible that sending a SIGABRT to the large process will give you some backtrace information about what it's doing, perhaps it's stuck processing a request. This ought to be logged to Apache's error log.
You can also try tuning the problem away by limiting the lifetime of Passenger workers, e.g. https://www.phusionpassenger.com/library/config/apache/reference/#passengermaxrequests

They are normal plugins, I think.
I have set passengermaxrequests to 50. I looks like I can tune that number up some, though.

Though foreman graphite is pretty recent. I may disable, as the info is not that useful.
Updated by Michael Eklund over 8 years ago
I let it run without recycling threads today and was able to get a backtrace with the SIGABRT, though it does not look that useful. I did disable foreman_graphite, so it is not that one.

What platform are you on? Can you do foreman-debug -u ?
Updated by Michael Eklund about 8 years ago
Ubuntu 14.04. I have hidden the problem with PassengerMaxRequests 100
I could schedule a time to make it happen and run debug when it grows if it will record useful info for you.

Hello,
I am having the same problem. After clicking the 'classes' button at https://foreman/environments one single ruby process consumes more than 50% of my 16GB memory. After restarting apache2 and closing the browsers tab the process was gone after some seconds.
I executed foreman-debug -u (but not while problem was happening):

We're seeing the same issue on our Foreman (128G memory, 10 physical cores, Dell R630). We do frequent hammer params searches as part of our tooling that utilizes Foreman on the backend. Bouncing httpd seems to restore the memory and stop the machine from swapping but it slowly creeps up again.
The offender is Passenger RackApp: /usr/share/foreman

and subsequent runs show the memory utilization under VMSize and Private continue to go up until memory on the system is exhausted. Currently we are working around the issue by restarting apache but this is not a viable workaround since it means the application is at times unavailable. What appears to cause memory utilization to continue to go up is a number of API calls (via other scripts run out of cron) that query foreman using e.g.:
hammer host list --search params.<some host parameter>=<some value>Kambiz

Final update here, looks like our issue was not related to memory leaks or passenger but instead a tremendous amount of new interfaces being collected via Puppet facts
and then pegging out Foreman to update host entries. We had upwards of 30,000 interfaces picked up across 48 x hosts.
We took the following steps to cull this and we're running a lengthy hammer process to remove them all.
Under Settings -> Provisioning: Ignore interfaces with matching identifier [ lo, usb*, vnet*, macvtap*, _vdsmdummy_, docker*, veth*, ens*, virbr*, br* ] Ignore Puppet facts for provisioning = true
