Exchange 2003 Priv.edb Growing 3 time in 2 days - Help

Hi,

We just switched our mail server from exchange 5.5 (due to 16GB Limit) to exchange 2003 enterprise two days ago. The new exchange 2003 has sp2 installed. However, since we switch, our Priv.edb database has increased to 24GB (1st day) and then 48GB (Today) and it is still increasing. I verified that our total size for all the mailboxs in priv.edb should be only around 17GB. Where did all these extra storage came from? Can someone please help me up? Please let me know what would cause this and how can I resolve it?

Note: we have been using exchange 5.5 for past 5 years and the storage grew to 16GB only. It is impossible for us to use up that many storage in two days!

Thank you so much!

First of all, disconnect the Exchange server from the clients (you cant disconnect it from domain controllers for its proper functioning), i mean just leave the exchange server talk to DCs and GCs and disconnect it from all other clients or application servers and see, if priv1.edb still growing. If yes, then there is a problem within Exchange.
Stop the SMTP service and see if priv1.edb still growing. Check if transaction log files are also growing with the same speed.

If not, then some client or application server is creating issue. Best is to use netmon to monitor the NIC on exchange and see, which IP is generating most traffic to the exchange server.

I have experienced similar issues with SMS server, MOM server or other 3rd party application servers doing this.

Thanks,

Hi aa230002, Thank you for your help. I will try the network traffic tool.

We actually set up this exchange 2003 2 months ago and the Priv.edb did not increase for the past 2 months. It only started to happen when we switched it two days ago. Some users do use "Exchange Cache mode" for their outlooks in this database, will this be the cause? Also, we create other edbs for other group of users which use POP3 and they were fine. Please let me know your expert inputs.

Thank you again!

Outlook 2003 in cache mode can not be responsible for increase in size of database file - priv1.edb .
A message getting looped up, a virus, or a spam attack can be some of the reasons.
So, first you need to identify if its something within Exchange (Stop SMTP service or disconnect it from all clients)
or some particular user or workstation or application server is doing this (Netmon trace)

Thanks,

The Priv.edb database stopped to grow at 48GB since 5/25. The online defragmentation showed that it has 29GB of free space now. I think it should be fine for now. 19 GB is about the total size for all the mailboxs in our priv.edb database.

However, I still have no ideas why the Priv.edb database increased so extremely in the first 2 days when we switched. Plus what spaces did online defragmentation free up for the 29GB. The 29GB must be the problem that increased the Priv.edb database in the first place.

Please let me know if you have any suggestions.

As i earlier said, there can be many reasons for this. Now, as it has stopped growing and Online Defrag has showed 29 GB of white space. To recover this space, you will have to run offline defrag. I would suggest you to just monitor the database and in case, it starts growing again, you need to go through the same steps to identify the root cause.

Thanks,
Amit Aggarwal.

Hi vran:

The Priv.edb database stopped to grow at 48GB after 2 days, and we had 29GB of free space.  The free space had been used up during the course of time when user mailboxes were growing but the Priv.edb remained at 48GB for almost 2.5 years.  My Priv.edb started to grow again slowly after it used up all the free space.  

Note: I did not perform the "offline defrag" because it did not increase after 48GB.

Hope this info help.
