  •  Hi Sankar,

    Best contact Cadence Support to see if they can lend a hand.

     Since it still happens in latest IUS62, it looks to me like it could be a really low-level OS/hardware issue.  Given that 2.4.x series kernel (versus more current 2.6.x series), my first suspicions would be that you're running too old a flavour of Linux for the hardware (x86_64, SMP). 

    ...Or perhaps you simply don't have enough RAM and/or swap space (to address the 'virtual memory limit exceeded' message).

    Andrew.
