Right now, I have absolute not traffic when testing this with my test script.
(I will do such test next days)

Here the filenames after some restarts:
(tested with VC15-patch-3-mod_slotmem_shm.rar)

1. Start with 3 Proxy elements 
slotmem-shm-p17ffdef3.shm
slotmem-shm-p17ffdef3_config.shm
slotmem-shm-p17ffdef3_home.shm
slotmem-shm-p17ffdef3_res.shm

2. Adding Proxy "a" with 2 BalancerMembers
httpd -k restart
slotmem-shm-p17ffdef3.shm
slotmem-shm-p17ffdef3.shm.2
slotmem-shm-p17ffdef3_a.shm
slotmem-shm-p17ffdef3_config.shm
slotmem-shm-p17ffdef3_home.shm
slotmem-shm-p17ffdef3_res.shm

3. Removing this Proxy "a"
httpd -k restart
slotmem-shm-p17ffdef3.shm
slotmem-shm-p17ffdef3.shm.2
slotmem-shm-p17ffdef3.shm.3
slotmem-shm-p17ffdef3_a.shm
slotmem-shm-p17ffdef3_config.shm
slotmem-shm-p17ffdef3_home.shm
slotmem-shm-p17ffdef3_res.shm

4. Adding Proxy "a" again with 1 BalancerMember
httpd -k restart
slotmem-shm-p17ffdef3.shm
slotmem-shm-p17ffdef3.shm.2
slotmem-shm-p17ffdef3.shm.3
slotmem-shm-p17ffdef3.shm.4
slotmem-shm-p17ffdef3_a.shm.4
slotmem-shm-p17ffdef3_config.shm
slotmem-shm-p17ffdef3_home.shm
slotmem-shm-p17ffdef3_res.shm

5. Adding 1 another BalancerMembers to Proxy "a"
httpd -k restart
slotmem-shm-p17ffdef3.shm
slotmem-shm-p17ffdef3.shm.2
slotmem-shm-p17ffdef3.shm.3
slotmem-shm-p17ffdef3.shm.4
slotmem-shm-p17ffdef3_a.shm.4
slotmem-shm-p17ffdef3_a.shm.5
slotmem-shm-p17ffdef3_config.shm
slotmem-shm-p17ffdef3_home.shm
slotmem-shm-p17ffdef3_res.shm
