Anyone seen this before? I'm running 11.2.0.1, 4-node RAC, on RHEL 5.3, x64-64. I'm seeing continual spewing of the following line into my alert log: ORA-1628: max # extents 32765 reached for rollback segment _SYSSMU29_3170879604$ Many, many times per second. This is happening only on one node. I checked MetaLink, and there's a bug, but it's supposedly fixed in 11.1.0.7, and the sample queries they have to run do not seem to indicate this bug. Anyone else seen this? Thanks, -Mark
