Return Error Code 402 with MSSQL

[itatcma]

What would cause this return code to be raised?
This is running the MSSQL application with Amanda 3.0.0

When job is running, monitor displays:
Backup Failed: dumper [return error code 402]

Summary Report includes:

FAILURE SUMMARY: SQL01 MSSQL lev 1 FAILED [data read: recv error: Connection reset by peer]
SQL01 MSSQL lev 1 FAILED [too many dumper retry: "[request failed: Connection refused]"]

"Data time out" value is set to maximum (but the failure occurs within 10 minutes of the start of the job)

In some executions, there is a "partial" backup and there have been successful backups. ... very erratic results.

I've received the same message - did you get a response for your old post or did you figure it out?
