I have a working Percona database server running multiple databases with mostly InnoDB tables (maybe a few hundred tables total). Any table that exists is working fine, yet I cannot convert any existing MyISAM tables or even create new InnoDB tables in any schema (even new fresh ones).
In fact I can trigger the crash (Error Code: 2013. Lost conenction to MySQL server during query) as minimally as this:
create schema testschema;
use testschema;
create table testtable (
testfield int(10)
);
(InnoDB is the default engine, and I get the same result making the engine explicit, while specifying MyISAM creates the table successfully.
What gives?
Some diagnostics:
cat /proc/$(pgrep mysqld$)/limits
...
Max open files 8192 8192 files
...
Starting from the crash, (large) error log has these possibly notable lines

A restart occurs which performs rollback and ens successfully, though the log does mention this InnoDB: Last MySQL binlog file position 0 18814, file name /storage/logs/mysql/mysql-bin.000005 and there is no binlog set up (this path no longer exists either).
