To Reproduce:

1. Deploy the project linked in the post (658439_BundleTest.zip).

2. Notice that, the last www, returns an error when trying to load an asset bundle:

'The operation couldn't be completed. (NSPOSIXErrorDomain error 24 - Too many open files)'

this doesn't happen if the same bundle is loaded without any other bundles.

Not sure what exactly causing this, tried generating (using the other attached project) a similar number of large bundles, bundles with a very large number of files, many small bundles, but couldn't reproduce this, when loading bundles not from the initial report.
