Alternatively, you can also upgrade your
OpenOffice
to a correct version compatible with SELinux
in Red Hat Enterprise Linux 5. You can do this by subscribing to the "Productivity App" child channel
in Red Hat Network and running the following command:
yum install openoffice-
{base,calc,draw,emailmerge,graphicfilter,headless,impress,javafilter,math,pyuno,writer,xsltfilter}
• If jumbo frames are enabled on your system, a kernel panic will occur if you attempt to unload the
bnx2
module.
• Red Hat advises that you avoid removing a block device from a guest while the device is in use.
Doing so causes Xend to lose domain information for the guest.
• Accessing the right-click menu of the
NetworkManager
GNOME applet may cause the GNOME
Keyring Unlock
dialog to appear. When this occurs, no XII applications can receive keyboard or
mouse input.
To recover from this, switch to a virtual terminal using
Ctrl
+
Alt
+
F1
. Log in as the affected user
(or root) and run
killall -9 nm-applet
. Then, switch back to X11 using
Ctrl
+
Alt
+
F7
. Your
system should be able to receive keyboard and mouse input, although Red Hat recommends that
you logout and login again to allow the system to fully recover.
• On Altix systems with an ATI FireMV graphics adapter, the GUI console may not display on one
of the VGA connectors. To workaround this issue, switch to using the other VGA connector on the
dongle.
• It has been determined that 1024 byte objects in kernel slab may be lost when a call to pipe() fails.
The problem occurs because pipe() allocates pipe files, and then tries to get free file descriptors for
them. If the process is out of file descriptors, pipe() fails, but it does not clean up properly. A fix for
this problem is planned for a forthcoming 5.3 kernel update.
To workaround this issue, ensure that the process calling do_pipe has adequate file descriptors
allocated.
This issue has been observed with
multipathd
in particular. To avoid the problem with
multipathd
,
calculate the number of file descriptors (FDs) required using the formula: "FDs = Number of Paths
+ 32". If the result is greater than the default value of 1024, then the max_fds value in the defaults
section of multipath.conf should be set to the previously calculated value. For example, if there are
255 LUNs with 8 paths each, the line to be added to the defaults section of multipath.conf would be:
max_fds 2072
• The
libcmpiutil-devel
package depends on
tog-pegasus-devel
, which for the Red Hat
Enterprise Linux Desktop product is only available from the Workstation option. Therefore, any
