Getting exception while trying to save data into Decision Data Store (DDS) using Data Flow in Pega Marketing 7.3.1

As part of our Decisioning application, we are storing customer info into Decision Data Store using a DataFlow. It was working fine.

Suddenly, we started to have problem in saving the data and it waits for 30 secs and throw the following exception.

Environment : PROD

Pega Marketing 7.3.1

Nodes: 2

DNode is up and running on both nodes.

Any help is very much appreciated

Hi Saravanan,

Can you verify if you are running out of disk space on DDS nodes?

I would suggest you to raising a support ticket for further investigation.

Thanks & Regards,

Santhosh
