Gutis's techdoc reference earlier has a value referred to it. Can you check the option on your setup and see what the value is?
Worst case, You could try disabling the web response completely and see if that reduces the burden a bit? This would be the last chance option I would consider:
To disable the threshold follow these steps:
To add the variable to the nx.env run the following command:
pdm_options_mgr -c -s EXPECTED_WEB_RESPONSE -v 0 -a pdm_option.inst
To add the variable to the nxenv_nt.tpl file run the following command:
pdm_options_mgr -c -s EXPECTED_WEB_RESPONSE -v 0 -a pdm_option.inst –t
