Assertion Errors:

[crispin.proctor]

Hi All,

I have started getting Assertion Errors in SQL.
It appears when I process a cube (Most of the time)
Other SQL statements, usually with a join or 6 do the same thing.

Whaving a scratch around google, I noticed the most people who get
these errors are using SATA drives. Either RAID or not.
Surprise, I am using SATA in RAID 1.

Is this a common thing with SATA? I can't go to the pwers that be and
say I need a couple large SCSI drives because I _think_ it's the
SATA's.

Another very odd thing that happened thismorning was I copied the mdf
and ldf files off my machine (About 70GB) and onto the server. attached
them and SQL was happy.
Select Count(*) from aview gave me the count I was expecting.
Select * From aview returned no rows. most of the time.

I thought I was going mad. F5 works, then it doesn't then it does then,
you get the point.
Backup and restore seemed better until the errors below started...
HELP!!!!

Thanks
Cheers,
Crispin

Thanks Simon,

Problem is the checkDB does the same thing.
We have replaced the drives, drive controller etc.
Even replaced the mother board.
Only thing I have not replaced on the machine is the mouse :)

My concern is we have shipped some servers to client with a simlar
config. (SATA drives running RAID 1)
Now if this is a limitation of SATA I am in a world of sh1t.
We use SATA drives as a cheaper alternative to SCSI for some clients.
I reasoned they would be faster than IDE and if Dell, HP etc have SANs
running on SATA drives, they can't be all that bad.
arrrrggggggg. This is killing me. It's actually gettiing worse. Run the
diagnostics on the drives and no error's reported.

Cheers,
Crispin

The KB article that Simon referred you to, suggested that you should
open a case with Microsoft, and I would encourage you do that.

Assertion errors are always bugs in SQL Server in the sense that they
should not occur. But it could be that instead you should have gotten
a better error message. In your case, it appears that your database is
corrupt. (Which could be due to a previous hardware error.)
