How to handle this Data Abort exception in ARM 7?

Question

I am working on ARM 7 board and facing data handler related issues i.e. many times board got stuck at 0x10. I checked CPSR register and found mode is 0x17(Abort mode). How to handle this Data Abort exception in ARM 7? I tried to configure in exception vector but it failed. Also the R14(Linked Register) is different at every time.

Using IAR. Data Abort occurring after servicing many IRQs for long time.
