NetBackup status code: 24

Message: socket write failed

Explanation: A write operation to 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.

A possible cause is a high network load. For example, this problem occurs with Cannot write to STDOUT when a Windows system that monitors network load detects a high load. It then sends an ICMP packet to other systems to inform them that the route those systems use was disconnected. The log messages were similar to the following:

01/31/96 14:05:23 ruble crabtree.null.com from client

This error may occur during a restore to a Novell client.
Note the following possible actions:
- By default, the value for Novell "Maximum Packet Receive Buffers" may be too low (such as 100). To improve the restore performance, change this value to 2000. To change it, issue "SET Maximum Packet Receive Buffers=<value>" at the console, or enter the value in either of the following Novell files: sys:system\startup.ncf or sys:system\autoexec.ncf.
- 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
```
