Wrong my.cnf section?
It should be under [mysqld].

[vavr]

Here is my my.cnf - it almost a default:

$ cat my.cnf 
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...

В mysqld.log ничего нет? Модуль точно загружен?
MySQL ругается про опции, которых не знает.
Не знает он опции, если модуль не подгружен.
Как может получиться, что модуль подгружен, но опции он всё равно не видит - мне неизвестно.

[vavr]

Приношу свои глубочайшие извинения :)
Оказалось что в строке "pinba_stats_history           = 60" имеются какие-то непечатные символы. Написал заново строку - все заработало. Еще раз прошу прощение.
