Re: memory leak with "in memory" storage?

After allocated the memory using my_malloc, msyql use my_free to free the memory, and the behavior of my_free depends on the library mysql used. Some library just doesn't release the memory back to OS with the hope to reuse it later.

We faced the same problem on solaris, the default library mysql used and the mtmalloc won't really release back the memory to OS. You may try to find a different memory allocator that could release the memory back. One of my workmate tested mysqld on linux and found the memory could be released back to OS which is the opposite of what you experienced. What memory allocator did you use?
