What do the wait events 'gc cr failure' and 'cr request retry' mean?

520833Apr 22 2009 — edited Jan 4 2011
I'm trying to troubleshoot an issue for a customer. Environment is Oracle 10.2.0.4 (64-bit) on Redhat 5. Two node RAC cluster. The 10046 trace file shows lots of 'gc current block 2-way' waits but also a few 'gc cr failure' and 'cr request retry' waits. The 'cr request retry' waits take about 0.9 seconds each. I cannot find much if any information on these two wait events. Any help is much appreciated.

Thanks!
