Likelihood of Occurrence

Possible Symptoms

The symptoms can include:
- process failure
- startup failure
- processes spinning in function sskgxp_select with high CPU usage
Workaround or Resolution
There is no workaround available. However, if the instance fails to start, a reboot of the server supporting the instance will usually allow startup to succeed.
Patches
At the time of writing, patches were under development on top of 10.2.0.4 on some platforms. Please check Patch 7331323 for availability on your platform.
