Subject DO NOT REPLY [Bug 52402] balancer setup crashes apache during start

It looks like each balancer creates the SHM for its number of workers (1
in my case) using its unique ->sname. After that, each worker grabs a
slot from this.

I have several virtual hosts pointing to the same balancer (by rewrite
[P]). So, the second time, the balancer calls shm's slotmem_create again
with its name, that already exists -> kind-of noop.

Now, the SHM under the balancer's name has still only 1 slot (that is
already occupied).

When the worker now wants to (re-)grab its slot, I get:

[slotmem_shm:debug] mod_slotmem_shm.c(575): AH02293: slotmem(...) grab
failed. Num 1/num_free 0 [proxy_balancer:emerg] (22)Invalid argument:
AH01186: worker slotmem_grab failed

Does anybody know the intention behind this?
