Server crashes on 'show table status'

Hello,

We seem to have a strange issue where running 'show table status' takes 3-4 minutes and then crashes the server.
The server is used largely with TokuDB with quite a few partitions.
We have had other errors with too many open files, but those are intermittent and I am not sure if they are related.

I have attached the error log during the crash and the server parameters in the attachment to this ticket.
