Hi,

In FW version xx.32.1010 we introduced a configuration parameter to limit this number of resources (reduces required resources from the host system):

[" QP Resources"]

You can use this parameter to increase that value to what is required by your application.
If you do not find this parameter available in the query command please update MFT package to at least v4.18.0.

Regards,
Yaniv
