Transaction logs being created every 10 mins 1

[Daniel101]

Hi,

I am wondering if anyone can help me. We have had our server running exchange 2003 for about a year and a half now. Every day the transaction log (5Mb) is created and we clear this out regually.

Over the last week the server has started creating a transaction log file every 10 mins or so. This is causing problems as it is filling up the HDD very quickly.

Does anyone have any uggestions to resolve this issue.

Regards

1. How do you clear out the transaction logs? The proper way is to do a full online backup with an exchange aware backup program. This will truncate committed logs on completion.

2. Have you noticed an increase in mail flow? Writes to the exchange database are first witten to log buffers in memory. From there, they are persisted to disk in the form of log files. By default, each log file is 5mb. In addition to the logs themselves, you have an edb.chk checkpoint file that keeps track of what has and has not been committed from the logs to the database. When you do a full backup, logs containing only committed transactions are truncated or removed. If you are backing up on a regular interval, the log files you see represent the volume of changes, or your change delta, since the last backup.

3. If you can correlate the increased logging rate to an increase in mailfow, this might not be an indication of a problem. If you cannot, then you need to investigate possible message looping.
