Jiri, note that this happens on startup. In fact it runs out of mem.
when it tries to alloc. a chunk of memory big enough to hold all the
 entries in location. This is not a memory leak and it really happens if
 PKG_MEM_POOL_SIZE is 1Mb and you have >6000 entries in location (it
 depends of course on your average entry size, but the critical point is
 in general between 6000-7000).

This could be a mem. leak (but this is unrelated to the startup
problem).
