Comment 4 Devendra Singh 2021-09-13 14:47:39 UTC
Verified on 6.9.6 Snap2.

1- Created the base version of the Satellite setup using 6.9.4 GA template.
2- Checked the thread FOREMAN_PUMA_WORKERS, FOREMAN_PUMA_THREADS_MIN and FOREMAN_PUMA_THREADS_MAX and they were 2, 0, and 16 respectively.

# systemctl cat foreman.service
# /usr/lib/systemd/system/foreman.service
[Unit]
..........
..........
Environment=FOREMAN_PORT=3000
Environment=FOREMAN_PUMA_THREADS_MIN=0
Environment=FOREMAN_PUMA_THREADS_MAX=16
Environment=FOREMAN_PUMA_WORKERS=2

3- Ran the upgrade from 6.9.4 to 6.9.6 Snap2.
4- Upgrade completed successfully.
5- The CPU and Memory of this machine were 20Gig's of RAM and 6 Core CPU.
6- As per the puma documentation, the size of the worker should be a multiplication of 1.5, On this setup, we have 6 cores hence the worker count is 9 correct.

6 * 1.5 = 9
