On earlier builds of BIG-IP software (specifically, version 14.0.0 and earlier), TMSH might allow vCMP Guests with 8 GB or less to provision more than three modules, even though the recommended practice counsels against doing so. Upgrading a system with a vCMP guest configured with more than three modules results in a 'failed load,' as returned in 'tmsh show sys mcp' command results. This configuration might potentially cause out-of-memory problems once traffic is passed.
Possible out-of-memory errors on BIG-IP systems once traffic gets passed.
-- vCMP guests with 8 GB RAM or less. -- Four or more modules provisioned. -- Upgrade the system.
Provision no more than three modules on 8 GB RAM vCMP guests before upgrading. If more than three modules are already provisioned, before upgrading vCMP guests with 8 GB or less of RAM, remove provisioning on some modules to ensure that there are no more than three modules provisioned before upgrading.
The process halts with an error when attempting to provision more than three modules on vCMP guests with 8 GB or less of RAM.
In earlier releases, you could provision more than three modules on vCMP guests with 8 GB or less of RAM. Now, the provisioning process halts with an error when attempting to do so.
