Hi Björn, thanks for your support. I monitored the semaphores and shared memory the way you described. With the following results: Right after Apache restart: ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x0115859c 26116096 root 600 682600 5 ------ Semaphore Arrays -------- key semid owner perms nsems 0x00000000 2359296 apache 600 1 0x00000000 2392065 apache 600 1 0x00000000 2424834 apache 600 1 0x00000000 2457603 apache 600 1 0x00000000 2490372 apache 600 1 0x00000000 2523141 apache 600 1 0x00000000 2555910 apache 600 1 0x00000000 2588679 apache 600 1 0x00000000 2621448 apache 600 1 After apache stopped working: ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x0115859c 0 root 600 682600 12 ------ Semaphore Arrays -------- key semid owner perms nsems 0x00000000 0 apache 600 1 0x00000000 32769 apache 600 1 0x00000000 65538 apache 600 1 0x00000000 98307 apache 600 1 0x00000000 131076 apache 600 1 0x00000000 163845 apache 600 1 0x00000000 196614 apache 600 1 0x00000000 229383 apache 600 1 0x00000000 262152 apache 600 1 I'm not the real freak when it comes to semaphores and shared memory usage. Can you see something suspicious there? Another notice: After reading your reply I deactivated eAccellerator, ionCube-Loader and Zend-Optimizer, so that PHP runs without any additional caches or optimzers, Unfortunately this didn't help and apache stopped working again.
