Hi GulfIT,
Exchange SP?

All the backups are running smooth with no failures?

You need to find what's going on with your server for that you will need some tools to help you, EXmon, Log Parser Studio.

You could find here some help on how to troubleshoot.

Let us know if helped.

Do you mean the folder itself is growing 100MB a minute?  Because transaction logs in 2010 are 1MB.  Just making sure we're talking about transaction logs as you state the "files" are growing 100 MB a minute.

How large is your store?  Anything in the event logs seem off?  Do the logs flush with a good backup?

I have a couple of stores both 100GB each and te logs folder is increasing at 100MB per minute.

Tried using the tools mentioned but could not point out a particular user burdening the system.

I don't honestly think 100mb a minute is all that bad.  I just looked at my server and we're running about 75 meg a minute from 8:05am-8:52am, so the company is still waking up.  I'll beat we beat 100mb a minute shortly.  Our store is 130 gigs.

As long as the logs are flushing out with a full backup, I think you're fine.  We actually use Shadowprotect and perform an hourly backup (Takes seconds) so we never have more than an hour's worth of log files anyway.

Actually its been increasing throughout the day and at a consistent pace. It seems that some process is triggering the increase cannot figure it out.

I would expect it to increase throughout the day as workload increases.  

One thing you could TRY for a very short-term test (Few minutes) is turn off ActiveSync.  See if that changes anything.  Could be a problem phone.

please see to the below link, if you have enabled Circular logging.


Also try to use a backup that would flush the transaction logs.

Seems that it was a corrupted MB store that caused the issue Ran a Integrity check and the issue is now sorted out.
