This might not be a good suggestion but have you thought of knocking down modulation temporarily to see if anything changes? I know you're saying SNR and FEC are fine but it might be worth trying....

Hello, Does anyone know what the best things to do when you have speed problems with cable modems in different downstream/upstream? This is the scenario: uBR 10K with about 17000 customers. Each downstream is configured with 256qam and all upstream have 16qam of modulation. In some cases the upstreams have a load-balance configuration with 2 or 3 upstream per optical node. There are no problems of SNR and FEC. All values are regular... And the used bandwidth are low.. After that, in some upstream can not go to the 20Mb of download Bandwidth and with the configuration used, should arrive without problem to 37Mb... I tested several cable modems and the problem still remain ... Someone has suggestions or ways of action to overcome this type of problem?
