    Hi Pando,

    What Pando is saying is apply patch 8.1.7.4 There was a memory leak intermittiantly(sp) in the privious releases that wasn't fixed until .4 of course if it's still present, after you patch it. Oracle is just going to tell you to upgrade to 9i or 10g anyway
    but I must say I haven't heard of any memory leaks in .4 anyone else?

    If there was no ora-600, Oracle shop would have been closed long time ago.

    I'm sorry I couldn't resist it's just too good to pass up.

    You do if you run Windoze. Patch level 8.1.7.4.1.

    Metalink suggests the leak can be ignored if it's "small"
