It seems that it is happening because of the way the database is created. On an old database it runs perfectly fine or if I use the old DB as template to create the new one, it  runs fine. But if I create a new DB with same settings and permissions it hangs. I'm now trying to find the difference between these 2 databases.

Thanks & Regards,

There's lots of areas where you could be running into problems. I
suggest reading this wiki page on reporting performance problems.
It'll help you gather more evidence of where and what the problem is.
