Oracle claims to have fixed the leak in 9.2.0.4 and 10g (Bug #3519807). (Mark - you're running 9205 and you confirmed the leak) I reOpened my iTAR and will press them harder this time for a fix. Is anyone on OraDev reading this? Interesting enough, we traced ADDM and it does not use the x$ksolsfts structure, yet creates a horizontal structure for segment statistics that is deallocated when ADDM exits. Maybe OraDev knows it leaks? The long and short of it seems to be: when select * from v$segment_statistics is typed, 1400 bytes of shared pool goes poof! That smells bad. Granted, there are cases where we can run the query in a test loop and not leak memory, but it is unpredictable, even on the same instance (and usually does leak). __that's our findings -----Original Message----- From: Powell, Mark D [mailto:mark.powell@xxxxxxx]=20 Sent: Tuesday, December 21, 2004 12:57 PM To: Daniel Wittry; oracle-l@xxxxxxxxxxxxx Subject: RE: Statspack (shared pool) memory leak I ran your script a dozen times or so (9.2.0.5 64 bit RAC on AIX 5.2) and sure enough 04031 errors starting poping up. Unfortunately I do not have any more time to look at this, but perhaps one of the board guru's will look. I was wondering if you have brought this issue to Oracle support attention? -- //www.freelists.org/webpage/oracle-l
