Мне кажется, что на этот вопрос тебе сможет ответить... Только ты сам ))) По-моему, на этом форуме главный специалист по valgrind - это ты  ;D Твой вопрос довольно узко направлен, ты не показываешь код приложения. Без этого довольно сложно анализировать. Кроме того серия твоих вопросов напоминает отладку твоей конкретной программы силами сообщества, при этом никто кроме тебя не понимает о чём речь. Очевидно, что у тебя более 50 потоков, при этом возникают некоторые проблемы с памятью, но это всё что можно сказать. В любом случае - это не очень культурно, как мне кажется. Потому что ответ на твой вопрос требует глубокого поиска с погружением в конкретно твою проблему с её спецификой, за твоё "спасибо" в лучшем случае.
Мой совет - если подозреваешь, что проблема в библиотеке - поищи информацию об этом в сети, но это не очень вероятно. Если некий кусок твоего кода беспокоит - выкладывай на обсуждение. Но не проси помогать тебе отлаживать каждую строчку твоей программы ;)
Кроме того, по valgrind, наверняка существуют специализированные форумы (как и по libmysqlclient_r).
Кто-то же должен что-то делать...
