Hi Graham.

PKG_MEM_POOL_SIZE means fixed private memory allocated for each
kamailio process. You can edit config.h and set a higher value (i.e.
16 MB):
  #define PKG_MEM_POOL_SIZE 16*1024*1024

About SHM_MEM_SIZE that's shared memory for all the processes. It
value can be modified with the -m paramenter when running kamailio
command:
  kamailio -m 256

In case of LCR module with so many rules, indeed you need a high
shared memory value as rules are stored in shared memory.
And I also think that you need to increase private memory as well
since the database load task (gws and rules) is done using private
memory (hope I'm not wrong here).

Regards.
