Symptoms

Intermittently, the Inventory Supply/Demand form will hang for up to 30 minutes before returning requested data. Profile INV: RPC TImeout = 1000

Review of the Inventory Debug log file shows the form query only takes a few seconds to execute (i.e. does not seem to be a problem). The trace file shows the following as the only significant performance problem, but it is still not matching up to the amount of time taken by the form (i.e. it only showed 240 seconds of wait which is clearly no where near 30 minutes):

begin fndcp_tmsrv.read_R_pipe(:ec, :to, :typ, :enddt, :rid, :C_pipe, :nl, :nc, :dl, :secgrp, :usr, :rspap, :rsp, :log, :app, :prg, :argc, :a1, :a2, :a3, :a4, :a5, :a6, :a7, :a8, :a9, :a10, :a11, :a12, :a13, :a14, :a15, :a16, :a17, :a18, :a19, :a20);end;

All the latest patches had been tried to fix this problem and gather schema statistics had also been run. RDBMS version = 9.2.0.3.0 so <Patch 3110923> is not applicable
