- High CPU and memory consumption
-
Server load spikes when client systems check in to the server
-
Delay in Satellite packages being available to client
Environment
- Red Hat Network (RHN) Satellite 4.2.x, 5.0.x, 5.1.x, 5.2.x
-
Red Hat Network (RHN) 5.3.x if the default configuration for repository metadata generation has been changed from the default to mimic behavior on pre-5.3.x releases
-
Red Hat Enterprise Linux (RHEL) 5 clients checking in to the Satellite server via yum commandline or yum-updatesd, etc.
- Large deployment - environments with a high number of client systems registered to the Satellite are more likely to see the issue
