SQBCoreService.exe v 6.4.0.56 Crashes

The Backup Agent Service is crashing for me consistently on a new install of version 6.4.0.56. I have gotten backups and restores to work a few times but it fails more than succeeds. The error from the event log is below -- this running on Windows Server 2008 R2 Enterprise, SQL Server 2008 R2. Any help with troubleshooting this is appreciated.



Faulting application name: SQBCoreService.exe, version: 6.4.0.56, time stamp: 0x2a425e19
Faulting module name: inetmib1.dll_unloaded, version: 0.0.0.0, time stamp: 0x4a5bda0b

    We have had a few problems with inetmib1 in the SQBCoreService process and there is a patch that should prevent that:

    ftp://support.red-gate.com/Patches/sql_ ... 0_1014.zip

    That archive contains the SQL Backup Agent executable file (SQBCoreService.exe) and command line interface executable file (SQLBackupC.exe). To replace the existing SQL Backup Agent, do the following:

    - ensure that no SQL Backup processes are running
    - stop the SQL Backup Agent service, or cluster resource if on a cluster
    - rename the existing executable file
    - extract and place the patched SQL Backup Agent executable file into the same folder
    - restart the SQL Backup Agent service/cluster resource

    Let me know if the crashing error still occurs.

    Thanks Brian.

    That appears to have corrected the service from crashing however I have a restore process running that is just spinning now without any progress.

    It appears that the db files were created on the server so the SQB is definitely being read, but it doesn't appear to actually be processing any of the data in the file. The restore has been running for over two hours, I am not seeing any disk activity and the GUI is showing 0B processed. Any additional help you can provide is appreciated.

    No idea. You could try turning on SQL Server backup/restore event tracing - that may reveal that the SQL Server is stuck writing a checkpoint or something.

    I doubt it's SQL Backup as problems with the service tend to time out and/or throw errors at you like crazy.

    I have attempted to trace the backup but it is not providing any additional info. Once it logs that it is transferring data it stops completely (see below). I ended up stopping the service in order to stop the ghost restore process. There are a few additional symptoms that I am able to report now as well.

    1.) I have been able to restore a native backup to and from the same locations.
    2.) I am able to restore a Redgate backup that is local on the server. The problem appears to be somehow network related but is not manifested in native restores.
    3.) I am not sure if this item is related or not but we did have problems with the initial installation of Redgate's server components (and have duplicated the install issue on another server we are standing up). We ended up installing via the command line install.

    I am trying to troubleshoot the install issue on the other server (maybe it is related to this thread) and am wondering is SQL 2008 R2 Enterprise running on Windows Server 2008 R2 Enterprise supported? I don't see any reference to SQL 2008 R2 in the documentation. Maybe that is why I am having problems with server components?

    SQL Backup 6.4 supports SQL Server 2008 R2. Can you locate the SQL Backup log from the activity history in the SQL Backup Console and post that up as well?

    There is no record of the backup attempt in the activity history.

    Can you try patch 1028?

    Looks like we are getting there. I was able to restore a very small database successfully however am now attempting a midsized db restore and getting a Preemptive_OS_GetProcAddress wait type on the restore command. After 20 minutes it has processed 0 Bytes. From what I am reading this might be a bug in SQL related to executing extended stored procs. Do you know if there is a fix for this?

    Again, no idea. The extended stored procedure only relays commands to the SQL Backup Agent Service and relays the output back to SQL Server. The wait type is some OS resource wait. The only wait type I have ever see is MSSQL_XP. The only system resources it uses are mutexes and memory-mapped files. It must be waiting for one of these resources. Typically there is a timeout associated with all of these objects so it would not sit there waiting forever.

    Thanks again Brian. I have been working in parallel paths and think I have found the problem -- it was related to our SAN (hence the preemtive mode which didn't appear to ever resolve). I am now able to backup and restore without any problems. I appreciate all of your help, time, and patience.
