  • @Atila, it is a fresh installation, it works sometime, but sometime it throws db errors Apr 9 '19 at 8:41
  • Just to confirm - you've started with a clean database and not a restored (from a previous...) version? If you restored then see tridion.stackexchange.com/questions/19919/… Apr 9 '19 at 9:34
  • It is pretty common to see the above error in a restored database as @Dylan already pointed out. If it happens sporadically, it could be an issue with your database. Are you having any maintenance scripts to analyse your database stats? Can you check if all of your stored procedures are successfully compiled?

It looks like a typical Timeout error on a database pointing to lacking database maintenance or database upgraded or restored, It's expected to run the stats update.

The first thing to check is whether you have regular database maintenance performed? If not, do one (and start doing it on a regular basis, if possible daily) and try again. Database maintenance (Tridion specific) described here.

You could increase the timeouts as described here might help to resolve your issue.

I hope it helps


Have you tried restarting your CM database server and/or looking at the maximum database memory settings, like this? I had a similar issue and I noticed the CM database server was out of memory, so I restarted it to resolve the issue. Then I noticed the database memory settings were set to the default maximum...
