Arcserve Exchange Agent log file out of control

Does anyone know how to prune the dbaexch.log file?  Mine is over 3GB in size now.

What are the consequences of deleting or moving the file?

Go ahead no ill effect, it is used for recording backup history only.

The thing is to prevent it from growing again. The Exchange DB Agent was probably put in debug mode.

Here is the registry hack for it. In your case it is most likely already enabled and set to 1 so you need to set it to 0.

Exchange Agent in Debug

(Directory, Information store)

ABNT 9.0 / 11.0
HKEY_LOCAL_MACHINE \ SOFTWARE \ ComputerAssociates \ BrightStor ARCserve Backup \ DSAgent \ CurrentVersion \ agent \ dbaexch

EBNT 10.5
HKEY_LOCAL_MACHINE \ SOFTWARE \ ComputerAssociates \ BrightStor Enterprise Backup \ DSAgent \ CurrentVersion \ agent \ dbaexch

EBNT 10.0
HKEY_LOCAL_MACHINE \ SOFTWARE \ ComputerAssociates \ Cheetah \ DSAgent \ CurrentVersion \ agent \ dbaexch

ASNT 6.6 / 7.0
HKEY_LOCAL_MACHINE \ SOFTWARE \ ComputerAssociates \ ARCservIT \ DSAgent \ CurrentVersion \ agent \ dbaexch

ASNT 6.0 / 6.5
HKEY_LOCAL_MACHINE \ SOFTWARE \ Cheyenne \ DSAgent \ CurrentVersion \ agent \ dbaexch

With Parameters double click on the value Debug.
The DWORD editor will popup, change Data: 0 to 1.

Other acceptable data values = 2, 3, 4 (higher value generating the most detail in the log)

Result: for (directory, Information store) you will find:

dbaexch.log
dbaexch.trc

Very interesting... I have the exact same problem.  It crashed our server (filled up OS partition) twice in two days by expanding upwards of 4GB in size.  Last night it grew even though there was no backup running or scheduled which confuses me.  It grew to 4GB in one day without any backup jobs running on that server - that is insane!

RickWilson:  Has the above comment from davidmichel helped or not?  I have checked those entries in the registry on my server and all are set to 0 so I cannot figure out what the bloatation is from.  I am conisdering just setting a scheduled task to delete the file every morning but that is rather sloppy and I would rather fix the problem.  I have not found anything in the CA Support portal regarding this issue and I have simply uninstalled the Excahnge Agent for the time being.

I hope I am not 'threadjacking' it is just I have the identical problem and would like to help resolve this as well.

I checked the registry as well and it is set to 0 also.

I moved the log file to another drive with plenty of space a couple of days ago and have seen no ill effects yet.

I also notice that a new log file has not been created since then.

I take it you move the log file to another location via the registry (ie. the keys provided by davidmichel)?

RickWilsonAuthor Commented:
No, I just moved it in Windows Explorer.

I will be checking the timestamp on the file to see if it is being used in the new location or what...

BBG-BBGMCommented:
You might want to check the old location to see if a new dbaexch.log file has been created.  From what I understand, the Exchange Agent is not smart enough to detect the move to the new location.  It will see that the file does not exist and create a new one.  

It is possible that you have to go to the registry key for the dbaexch agent (see davidmichel's post) and there is an entry for the location of the logfiles.  I cannot verify this reg key because I have uninstalled the agent for the time being.  I will let you know if I find anything out.

No new dbaexch.log file has been created.

Does it only create that when a full backup is done?  I haven't done a full backup since moving the file.

BBG-BBGMCommented:
I am not sure.  Mine was created and grew out of control with NO backups running!  I bet it would have stopped if I had restarted the Exchange Agent service.  I think it was just 'stuck' processing something and writing to the logfile.  Too bad it was too large for me to open up and view.

If I were you, I would just keep an eye on it though, and see if it shows up.

Here is a program that will let you view that log. I've used it to view logs as large as 4gb, and it is fast.

For the log to grow so large without being in debug there must be some repeating message, and so it would be nice to know what those logs report.

The log file was recreated last night.  it is 1KB in size.

guess i better make it a habit to check on that regularly.

1k is right for a normal backup.

Hi,
I have had the same problem today due to the fact ArcServe switched to debug mode after a time sync issue on our servers. Arcserve created today a .trc file of 50 Go on the Exchange Server, that leads it to hang the reception from new mails. I found the link below:
