Memory is not instrumented in MySQL until version 5.7 (currently in development), so this does make your question a bit of a guessing game. I can see from inside InnoDB status, that it doesn't appear to be InnoDB consuming the memory (assuming you collected this from when the problem was occurring): Total memory allocated 26217103360; in additional pool ...

The recommendations about setting the size of the pool won't help fragmentation.

Use the maxmemory to set a limit to how much your Redis database can grow too. Failing to do so, Redis will grow until the OS will kill it once memory is exhausted (per your current experience). The usage of maxmemory should be coupled with maxmemory-policy - you can choose from different eviction policies depending on your use case's requirements. For ...
