Bus Fault Exception Trap

Hi,

I have another problem. Im developing a machine, but currently, I am encountering random freeze of the software. When I tried to debug it though Call Stack, I was able to point out that every time it happen, it goes to Bus exception trap.

I also noticed that when building my application, there are 2 unresolved warnings:
Warning[Lo007]: [stack usage analysis] at least one function does not have
          stack usage information. Example: "__VECTOR_TBL". A complete list of
          such functions is in the map file.
Warning[Lo009]: [stack usage analysis] the program contains at least one
          indirect call. Example: from "vBcrTsk". A complete list of such
          functions is in the map file.

I tried to search the net but I havent yet find any materials to understand and to fix the said warnings.

Also I would like to ask if possible, if you think that there is possibility that Bus Exception Trap is related to the said warning.

I also check the map file (attached here though I deleted most parts).
I like to understand what the STACK USAGE analyzer is saying.
There are two patterns I saw.

I hope you can help me with my problems.

Thank you.

Regards
Mike
