NetBackup status code: 23

Message: socket read failed

Explanation: A read operation from a socket failed.

Recommended Action: Do the following, as appropriate:

Check the NetBackup Problems report for clues on where and why the failure occurred. If you cannot determine the cause from the Problems report, create debug log directories for the processes that could have returned this status code. Then, retry the operation and check the resulting debug logs.
Corrupt binaries are one possible cause for this error.

Load a fresh bptm from the install media to try to resolve the problem.
The following information applies only to Sun Solaris:

Verify that all operating system patches are installed.

See the Operating Notes section of the NetBackup Release Notes.

Verify that the recommended service packs are installed.
This error may occur during a restore to a Novell client.
Note the following possible actions:
- By default, the value for Novell "Maximum Concurrent Disk Cache Writes" may be too low (for example, 50); Novell recommends setting it to 100. A value of 100 increases the speed and efficiency of the disk cache writes. It increases the number of write requests to be run at one time.
- Change to or add the following settings in the Novell sys:system\autoexec.ncf file:
```
SET Maximum Packet Receive Buffers = 4000
SET Maximum Directory Cache Buffers = 4000
SET Maximum Concurrent Disk Cache Writes = 2000
SET Maximum Concurrent Directory Cache Writes = 2000
SET Maximum Physical Receive Packet Size = 1514
```
- On Windows master servers, check the LIST_FILES_TIMEOUT value and ensure that this value is at least 1800.
