Hi together, I'm trying to get my reverse-proxy running with the new httpd 2.4.1, that aborts now with "worker slotmem_grab failed".
When looking at mod_proxy_balancer: 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 Please note that my explanation should only be considered as an educated guess for the reason of the error - there might be other obvious causes that I have overseen. Has anyone similar issues? Any suggestions?
