Another DB error? o.O
I think it's a conspiracy. I'd bet money the devs are really out stealing minerals from POS's and sticking bananas up Titian tail pipes.

I'm not massively sure Titian would have been too fond of that.

What happened today and last week was that the query optimizer came to the wrong conclusions about that would be the best plan of action for loading solar systems.
We were getting a bad query plan and index fragmentation does not change the results of the query compilation, but somewhere we hit a so called 'tipping point', a point where the query optimizer suddenly changes its mind on what is best to do.
This often happens due to the number of rows or pages in a table since that is what one part of the decision is based on. This also happens if there is a certain number of rows within the range the query has to scan or seek on and that's where statistics updating helps.
What we did was to override the decisions of the query optimizer and told it to use a certain way of comparing two tables.

Is that a subtle way of saying 'something broke but we ran the database engine tuning advisor in sql management studio and it seems to be working now'?
Yeah, I do that 
Edit: Worth going over the execution plans manually as well, its suggestions can't always be trusted.

Hmm, more like a subtle way of saying 'we are using something which isnt up to the job so occasionally we need to hit it with a big stick to get it to work'.

Why didn't you fix it last week?
If you know what the problem is fix it.

I wonder hom much performance could be gained by just dropping the MS servers and dabatase, and replace it with a Unix/PostgreSQL environment.
Yeah, it would probably mean that a couple of monkeys would be out of a job, and skilled people needed in return, but that never hurt anyone. (No, not even the monkeys in the long run!)
But meh, wont happen.. ========================== Nothing is true, everything is permitted. ========================== |

Well I see what your problem is - You've got the darn Flux Capicitor in backwards. Back this thing up to 88mph and you should be able to roll back to when this game was semi-stable.
I think we need somemore free skill points to help our optimizer deal with all the extended downtimes.
