Bug: ORA-4031 for subheap “KTC latch subh” in 220.127.116.11By Martin | January 25th, 2012 | Category: 11gR2, Bugs, Oracle Database | No Comments »
I just saw MOS Note
ORA-4031 After Upgrade From 18.104.22.168 To 22.214.171.124 With Leak in ‘KTC latch subh’ Subheaps [ID 1398984.1]
giving very little information about this bug. At the time of this writing, there is no patch available but I expect it to be in a few days. I have checked some 126.96.36.199 instances and found only one with > 60 MB for this subheap.
