Mixing Oracle Results with VOMRS.

Problem Description

The problem we have started to see since 1 June 2008 (no code change in vomrs) VOMRS server is a multi threaded process and it looks like from time to time when the threads are executing the same query at the same time one of the query ends up with:
    SQL exception(Exhausted Resultset)

    There are two examples (the second one reminded me of the problem we
    have seen before ....)


    Timer-3 and Timer-4 are two different threads here, they are trying to
    execute the same query at the beginning and it looks like Timer-4 is
    stuck and ends with the error and Timer-3 is continuing :

I have more disturbing situation though:

    Timer-4 and Timer-5 have issued the same query , Timer-5 died with
    Exhausted Resultset error, Timer-4 inherited Timer-5 Resultset!!!!!  
    Member_id returned for Timer-4 should be 868 and member_id returned
from
    Timer-5 is 1319, look what is in Timer-4 after Timer-5 is failed:

    pd,LCG_VOMRS_ATLAS_W.member_identities mi WHERE mi.member_id=1319.....
     ^^^^^^^^^^^
