SQL DB02 file space error

Dear All,

We have installed our ECC6.0 system with SQL server 2008 on windows

server 2008 R2. We have alloted enough disk space on server but in DB02

we can find data file at times shows error "No free space in file"

eventhough there are no activities done on the server. This error

message doesnt stay for long as message gets shifted from each datafile

status message. Please advice

Best Regards,
