Hi,
I think  is clear from the posted log that the problem is a php one, in
the memcache module probably. Just at the beginning
it tell you that it is traying to unmap a chunk and that this operation
fails because the pointer is invalid (maybe not a pointer to something
obtained through the cache?).
