Monitored the CSV data generation and processing on servers 11.154 and 11.131. Had a meeting with Eli about another optimization and fix to the new pos reader, which will solve the occasional issues encountered. Some transactions were not fetched from the pos database due to the last read time not satisfying the last_read condition. We will add another criterion to check the sys_trans_num, this will be applied on the new solution that we are testing.
