Description

I cannot access monitoring while garbage collection is running. I get this error returned instead of the page: "template: admin/monitor:52:15: executing "admin/monitor" at <.Pid>: Pid is not a field of struct type *process.Process"

How to reproduce:

1. Upload some repositories (so it takes some time to do garbage collection)
2. Run the garbage collection action in the admin
3. While it is running, try and view the monitoring page in the admin
