> That's an yaql expression consuming a lot of memory and nothing to do with heat-engine memory usage. I have not checked which one and why. But, you can increase(double) memory_quota (in bytes) for yaql heat.conf.
[yaql]
limit_iterators=10000
memory_quota=200000
From /var/lib/config-data/puppet-generated/heat/etc/heat/heat.conf after undercloud deployed: [yaql] limit_iterators=10000 memory_quota=200000 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: In large scale test, the overcloud heat stack failed while tried to scale out nodes from 200 to 250. Till 200 nodes, we didn't face any issues in overcloud heat stack. We hit the issue after adding 50 compute nodes in the stack which exists with 200 compute nodes. To reproduce the issue, we use two types of composable hardware with 50 node count (50x1029p & 50x1029u). Version-Release number of selected component (if applicable): Red Hat OpenStack Platform release 16.1.0 RC (Train) Red Hat Enterprise Linux release 8.2 (Ootpa) python3-tripleoclient-12.3.2-0.20200615103427.6f877f6.el8ost.noarch python3-tripleoclient-heat-installer-12.3.2-0.20200615103427.6f877f6.el8ost.noarch How reproducible: 100% reproducible in Scale lab. Steps to Reproduce: 1. Deployed and successfully scaled out compute nodes with 200 counts. $ openstack stack list +--------------------------------------+------------+----------------------------------+---------------+----------------------+----------------------+ | ID | Stack Name | Project | Stack Status | Creation Time | Updated Time | +--------------------------------------+------------+----------------------------------+---------------+----------------------+----------------------+ | 94a1e1aa-c10e-4597-8050-4c95b8118388 | overcloud | 5afea8d232064664b24278742e2cca22 | UPDATE_FAILED | 2020-07-01T15:35:11Z | 2020-07-03T10:06:18Z | +--------------------------------------+------------+----------------------------------+---------------+----------------------+----------------------+ 2.

Statistics: Heat memory usage during stack deployment: https://snapshot.raintank.io/dashboard/snapshot/N97mW02uo3lkw4LOsWWZ475kiohfU6ub Heat CPU process Usage: https://snapshot.raintank.io/dashboard/snapshot/8qbygU6WS27CV8M4AR2XC0Fdc0uTVaVu Actual results: Scaled test failed at 250 node count. Expected results: We never experience heat-engine memory issue in OSP16.0 scale test and we scaled 250 nodes without having performance tunning. So we would expect better heat-engine performance this time. Additional info: SOS report of Undercloud node will upload soon.
