Running sanity Checks can take 5-10m or just forever

We have a big scene were the running sanity checks take from 1 minute to 10, or just forever…
Sometimes it just takes 30 secconds and its all good, but most of the times its taking various minutes to complete
Is these bug known ?

If the sanity check gets stuck I would advise to turn off some of the checking where geometry is involved, usually that helps with the problem.

Under the Admin tab you can find the Sanity Check section with all the checks listed. Please try to disable a few like: No Material, Floor Generator, Forest Pack Camera Limit, Long Obejct Name, etc. where the check involves going through your scene and objects.
