I am storing things in a shared memory zone allocated with
ngx_shared_memory_add and allocating each slab with
(as these items don’t need to be locked particularly). The problem I’m
having is that I add the shared memory with exactly the amount I need.
However, the final large thing to be allocated fails, but after this a
more smaller things are also allocated without any problem. There is
space for it but it has a problem with a large chunk when space is
Does anyone know why this is or how to fix it? My guess was that nginx
structures the shared memory in a way that means there is enough memory
(which I have made sure there is) but it is not continuous.
