Error Message 2530

[GSC]

Hi,
I'm fairly new at this but I'm gonna give it a try.
I have a Server (BDC) that keeps giving me following error:
On secondary sites, this is \Sms\inboxes\colleval.box.)

Possible cause: Low disk space on the disk drive of the site server inbox.
Solution: Make more space available on that drive.

Now that Server has 1.14Gb free on C-drive, 2.48 on D and 32.9 on the F-drive. It's a NT4 server with SP5.
The "Primary" SMS Server is also a NT4 with SP6.
Free space on this server is like this: 1.39Gb on C, 4,95 on D, 15.8 on F, 8.13 on J and 33.2 on K.
Is there anybody that have any idea on what this can be?
I've searched the technet and various sites and came up with nothing.

Thanks in advance

I would like to see some more information:

Is the site server specified as a CAP?

On what drive is the SMS share (look in server manager)?
On what drive is the CAP share?

How many resources do you have in All Systems?

Have you created any Collections recently?
Is the Collection you created recently based on a query?
Is the Query you based on the collection functioning properly?

I'm thinking that you have a query run amok, and/or you have your shares on small drives.
