Description Ram Nainsingh Tiruwa 2018-11-14 20:58:25 UTC
Description of problem:
satellite installer disables Pulp_max_tasks_per_child in the capsule by default, but it does not disable in the satellite.

satellite 6.3.3

Fresh install system with satellite installed 

Ran satellite-installer -scenario=satellite

In capsule server /etc/default/pulp_workers Pulp_max_tasks_per_child is commented
# PULP_MAX_TASKS_PER_CHILD=2 

In satellite server /etc/default/pulp_workers Pulp_max_tasks_per_child is uncommented

PULP_MAX_TASKS_PER_CHILD=2

This leads to memory leaks on the capsule server

Comment 5 Perry Gagne 2019-01-14 19:04:43 UTC
Verified fix in sat 6.5 snap 11.

Pulp workers is commented by default during satellite install:

# To avoid memory leaks, Pulp can terminate and replace a worker after processing X tasks. If
# left commented, process recycling is disabled. PULP_MAX_TASKS_PER_CHILD must be > 0.

# PULP_MAX_TASKS_PER_CHILD=2

Comment 10 Bryan Kearney 2019-05-16 14:04:55 UTC
Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/25511 has been resolved.

Comment 11 Mike McCune 2019-05-17 04:22:53 UTC
We removed all instances of the configuration for PULP_MAX_TASKS_PER_CHILD as this configuration is no longer supported as it leads to deadlocks in task processing, see:

https://bugzilla.redhat.com/show_bug.cgi?id=1656340

if you are still seeing PULP_MAX_TASKS_PER_CHILD entries in /etc/default/pulp_workers on a Satellite or Capsule then that bug is not resolved but in our tests and internal lab hosts on fresh installations of Satellite and Capsules there is no more PULP_MAX_TASKS_PER_CHILD setting which is correct.

Going to close this out as CURRENTRELEASE but if you are seeing this configuration entry still, please re-open.
