@HarnishaM Workday connector using below entry to enable aggregation retries for the listed errors: errorsubstring
I am not sure if it will work for Webservice connector, but please try.
Also, is this error intermittent? or you are getting for every run. In that case, you might want to check your partitioning logic. If you do the execution without partitioning, is it working?
I believe Webservices connector cannot handle this OOTB. You might have to either increase the timeout in application config xml or ask the corresponding application team to increase the timeout time.
