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. > On 10/14/16 1:29 AM, Alex Vandiver wrote: > > For reference, your perl versions are not comprehensible.

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.
