Bug Fix Advisory Updated mm packages available

Advisory: RHBA-2002:273-09
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2002-12-12
Last updated on: 2002-12-11
Affected Products: Red Hat Linux 7.0
Red Hat Linux 7.1
Red Hat Linux 7.2
Red Hat Linux 7.3

Details

Updated mm packages are now available for Red Hat Linux 7, 7.1, 7.2, and
7.3. These updates change the type of semaphore used by the MM library, to
avoid filling up kernel semaphore arrays.

The MM library provides an abstraction layer which allows related processes
to share data easily. On systems where shared memory or other
inter-process communication mechanisms are not available, the MM library
emulates them using temporary files. MM is used in Red Hat Linux to
provide shared memory pools to Apache modules.

In the previous MM update (RHSA-2002:153) the type of semaphore used by the
library was changed to increase performance. This semaphore type has been
found to fill up the kernel semaphore arrays, which can prevent Apache from
starting.

All users are advised to upgrade to these errata packages.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
