$ perror 24
OS error code 24: Too many open files

You need to bump up the max files limit in your OS. It may be defaulting to
a small number like 1024. If you can't change that limit, edit your my.cnf
and lower the table_open_cache number. You'll lose performance though,
since mysql will have to stop accessing some tables to open others.
