Hi! We are currently developing a MT server (pthreads based, the main thread does accept() and push_back to a vector that the threads pick up work from, the threads share a global hash_map of cached information protected by a pthread_rwlock) and we seem to have an issue with confliting memory allocators (locking).
Our server is based purely on STL and we can get desent performance if we compile it using the GCC/libstd++ flag __USE_MALLOC but this seems to lead to high level of memory defragmentation since the server is bogged down after a while of high load. From time to time we alse get memory leaks that we can't pinpoint to anything else than fragmentation... Has anyone had this problem? I am sending this to the MySQL list since it seems like the problem arises in combination with the mysql client library. How does mysql allocate memory (treadsafety) and how could this collide with the approach that the STL/GCC 3.0.1 does things?
