Thanks Jim. We'll run those 2 dtrace if and when it happens again. Box has been rebooted and issue (which was seen 2 days in a row) has not re-occured. The workload has not changed. The virtual stays ~flat-lined all the time on the box because of the nature of the workload. The issue seems to re-occur every 60 days, so I think something is leaking, but I'm still convinced it's not system virtual memory.
Interesting what you say about the ISM/DISM stuff. The way we stopped DISM being used for Oracle 10g was setting the SGA MAX and TARGET to equal values in the init.ora etc.. and that stopped an ORACLE process per sid called ora_dism_xxxxxxxx on startup. Things behaved much better once we did that. We believed we were experiencing a known Solaris bug around DISM leak. We have since patched the system but not re-enabled the use of DISM. -- This message posted from opensolaris.org _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
