OK. I don't have this exact error, but I do see that MySQL 5.6.31 is supposed
to resolve an issue with InnoDB fulltext indices crashing the server.
So I think I'm waiting for 5.6.31 to enter Debian - hopefully before Wheezy
freezes or it will be messy.

Sorry, a typo on my part. I have Perl 5.22.2 installed, not 5.2.22.

I started at 256M, and slowly raised it to 4096M without success.
I will experiment with Debian Snapshots and see if I can roll back MySQL to
5.6.28, and report what happens.
