Unable to preview on AT 0.6.2

Just tried upgrading to the new authoring tool 0.6.2 and am getting a string of Mongo 'topology destroyed' errors when trying to preview an existing project. Is anyone experiencing similar?

Also I noticed the new version is taking up 1.4GB memory. Does this sound right? The previous used around 200MB.

We experienced MongoDB crashes on one of our servers but with an older version of the tool – 0.6.2 is only a small bugfix release and wouldn't affect the database side of things.

The errors in MongoDB's log included references to Too many open files.

It was resolved by upgrading our MongoDB patch version. Hopefully this is of some use.

Thanks Tom. Yes we had a bunch of 'too many open files' errors also when installing.

We've managed now to get it working after completely nuking the old db server and reinstalling the latest MongoDB - it didn't seem to like upgrading from old to new - so we had to backfill with a dump of data from the old. We're using MacOS which I believe has some open-file limitations so that might've been a factor.
