This is a show stopper for both UDP and RTP inputs. Allocating 64 kB blocks of
memory instead of 1316 bytes results in total memory waste of ~700 MB and no
socket buffer will help you if the box starts swapping.

At least for these inputs, the memory needs to be sized properly.

   With kind regards,
