Hi Vinod,
This issue are already discussed in many SCN threads. It is temporary bottle neck that that causing no free area in memory management like ztta/roll_area. If the dump occurred frequently every minutes with z* program then check with your ABAP team for recent variant include in that program or if the issue started with SAP standard program and roll memory area if fine then get help from SAP. it might solve during unload time of server. check the below parameter also and tune if required.
em/initial_size_MB
ztta/roll_extension
abap/heap_area_dia
abap/heap_area_nondia
abap/heap_area_total
