||The number of bytes that could not be written.
Unable to write the given number of bytes to the network layer. Note that writes may occur as part of any larger network
operation. For example, some network layers have sub-layers that perform several reads and writes as part of a basic operation
in the upper layer. The cause of a write error is usually one of the following: 1) The network had a problem that caused the
write to fail. Reconnect and retry the operation. 2) The connection timed out. Reconnect and retry the operation. 3) The other
side of the connection cleanly terminated the connection. Consult the client and/or server logs for errors that indicate why
the connection has been dropped. Consult the output-log errors and fix the cause, then retry the operation. 4) The process
at the other side of the connection was aborted. Consult the client and/or server output logs for errors that indicate why
the process was aborted. If the process was shut down by other than normal means, there may not be any errors in its output
log. Reconnect and retry the operation. 5) The system is low on resources, and cannot perform the write. Free up system resources,
reconnect and retry the operation. If subsequent retry attempts fail, consult your network administrator.
