Description Jonathan Kamens 2002-07-15 19:55:14 UTC

It appears that mm-1.1.3-7 doesn't use SysV shared memory or semaphores.  I
think it should be configured with --with-shm=IPCSHM --with-sem=IPCSEM.

Comment 1 Nalin Dahyabhai 2002-07-24 19:05:52 UTC

1.1.3-7 uses IPCSHM shared memory and fcntl semaphores.  Forcing IPCSEM in
1.1.3-8 and later.

Comment 3 John Newbigin 2002-10-16 08:19:30 UTC

On Rh7.2, this causes breakage when the kernel runs out of semaphores.  running
php scripts directly leaks semaphores like a sive (2 per execution) and can
consume all available semaphore arrays in next to no time.

Until the bugs in php are fixed I will have to revert to the previous mm version.
