Hello Rainer, all instances have different DefaultRuntimeDirs, I have also checked problems regarding the generated *.shm and *.uid-files, but these files are definitely not the problem.
The problem here is definitely inside the shared memory of the os (command: ipcs), only if there is shared memory or semaphore reserved on the requested address the apache comes up, whether or not *.shm files are existing inside the DefaultRuntimeDir.

Can you try DefaultRuntimeDir ?
