    yes that's normal
    it the transaction logs for Exchange. There is the ability to turn on
    circular logging, but it is generally NOT recommended. The log files are
    vital for recovery. If you have not place the edb/stm (database) files on
    a drive (spindle not partition) separate from the log files, the recovery
    is less likely to be important to you.

    do a backup. full backups will truncate (delete) the transaction logs. do
    it soon too. Once you have used all of the space on the drive that holds
    tha logs, Exchange will use 2 reserve logs (*.res) and once those are
    full, the store will stop. No more mail till you clean out some space.
    Read the books on line (help files that came with Exchange) or grab teh
    disaster recovery guides from the microsoft web site for more details.

    For MS exchange server transaction log file the default
    size is 5MB and if the file is filled with transaction
    logs the storage engine will create an another new file
    and it will writes the new transaction logs on that file,
    this is look like a chain reaction. And it may be eat up
    your entire hard disks.

    To tally this type of problem, you have to enable
    CIRCULLAR LOGGING option. By enabling this, a single
    transaction file having 5MB will be overwritten by a
    storage engine again and again without creatine a new
    Transaction log files.

    With regards
