Hi Prafulla,
This is a common error when the space available for the shared memory area is not high enough (you'll need to increase parameter abap/shared_objects_size_MB in RZ11). You should get in touch with your basis guys and apply recommendation from the following OSS note:
1281896 - High Memory Consumption and CRM Webclient
Also depending on when this dump occurs (for example when using multilevel categorization) you might want to check if some OSS notes are relevant for your system, like this one for example:
1773567 - Multilevel Categorization: Out of Memory Exception
Best regards,
Nicolas.
