About every 2 weeks the server running NSM runs out or memory. ndsd stops and nsmengine is shutdown.

Here is example from /var/log/messages.

Aug 4 02:06:58 lin-rs kernel: <ffffffff80165c11>{out_of_memory+408} <ffffffff80167b57>{__alloc_pages+613}

Aug 4 02:06:59 lin-rs kernel: Out of memory: Killed process 6643 (nsmengined).
Aug 4 02:06:59 lin-rs kernel: Out of memory: Killed process 6644 (nsmengined).

Any thing that I can check?

Also, planning to upgrade to latest NSM version.

thanks,
Lin
