Data Warehouse "Requirements" Job Fails Every Night

Greetings,

Ever since we upgraded from 401 to 405, the "Requirements" Data Collection Job has failed almost every night. It runs for about 2 hours and 40 minutes. I notice errors in both the jts-etl and jts-etl-driver logs at the time of failure:

java.sql.sqlexception: com.ibm.rational.etl.common.exception.etlexception: java.net.socketexception: Connection reset

Any ideas what would be causing the connection to be reset/this failure to occur?

Thanks,

Dave
