When you upgrade an OES server that is configured as an SLP DA to OES 11 SP3, the DEFAULT SLP scope gets added to the slp.conf file along with the SLP scope configured by you. This might result in adding extra load to the OES server.
To prevent the extra load, remove the term DEFAULT from the following line in the /etc/slp.conf file, and restart the OES server for the changes to take effect.
net.slp.useScopes = DEFAULT,<slp scope configured by you>
NOTE:This issue is not applicable to OES servers that point to an SLP DA or whose SLP scope is DEFAULT.
This issue will not be seen in upgrades from OES 11 SP3 to future OES releases.
