MDM.exe and oracle.exe ....memory leak.. not releasing Nonpaged memory

We are facing Memory leak in oue MDM server. Our environment details

are as follows;

MDM 5.5 SP5 ( Build 5.5.41.70)

Oracle 10.2 patch 2

windows server 2003 SP1

XI 7.0 SP 9

If server is running continuously 3-4 days then Nonpaged memory is

getting exausted and server does not respond. Now we have to retart the

windows server manually.

If we see the task manager it is shows more than 200,000 handles for

oracle.exe and more than 100,000 handles for mds.exe.

1: Oracle.exe -- more than 200000 handles ( Approx >5000 is problem)

2: Mds.exe -- more than 100000 handles ( Approx >5000 is problem)

Since these applications are not releasing the handles properly so all

nonpaged memory gets exausted and server stops responding.

If we restart the mdm server, database and OracleserviceMDMD, then

nonpaged memory is released. But some times even if we restart these

services, we do not get nonpaged memory released. So we have to restart

the windows server.

please help me if anyone else have faced the same problem.

regards

Saurabh

    Hi Saurabh,

    What operations are you performing on the server? We investigated and found a few operations that are not correctly releasing the handles to the database, but you would have to be continuously, repeatedly executing these operations to see such a spike in the handles. Are you using Import or Syndicator? Any help you can provide is really appreciated; it seems like you may have found a real problem with the software.

    Thanks!

    Hello Saurabh,

    SAP developers have discovered a connection leak that is probably

    what you are seeing and the leak should be either gone or vastly

    reduced for MDM 5.5 SP6.

    If you could can describe what activities caused the leak you noticed

    (as Cleopatra discussed) we will use that as a basis to test for any

    leaks that remain.

    Thank you for your report,

    Dave

    Hi Saurabh,

    Are you running MDM 5.5, Oracle 10.2, MSSQL and XI 7.0 on one physical machine?

    Regards,

    Lev

      SAP has suggested us to migrate the win2003 32 Bit to 64 Bit machine.

      So planning for migration. Reason is that win 32 Bit m/c can have max 3 GB of memory. if we use PAE for memory extention on win 32 bit m/c then MDM does not understand how to address that memory. So even if we use more than 3 GB memory, for MDM effectively it is only 3 GB.

      regards

      Saurabh
