Description Jonathan Kamens 2002-07-15 15:55:14 EDT
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 15:05:52 EDT
1.1.3-7 uses IPCSHM shared memory and fcntl semaphores.  Forcing IPCSEM in
1.1.3-8 and later.
Comment 2 Mark J. Cox 2002-07-31 04:51:38 EDT
An errata has been issued which should help the problem described in this bug report. 
This report is therefore being closed with a resolution of ERRATA. For more information
on the solution and/or where to find the updated files, please follow the link below. You may reopen 
this bug report if the solution does not work for you.

Comment 3 John Newbigin 2002-10-16 04:19:30 EDT
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.
