java.net.SocketException: Broken pipe

Broken pipe errors are most often caused by the following three things:
The network drops while the Content Server is attempting to communicate.
The user cancels the request.
The database is down or refuses a connection.
Other conditions may also result in broken pipe errors, for example, archive replication mis-configured between two Content Server clusters.
Investigate network issues, ensure that users are not canceling requests which are in progress, and/or check the database availability.
