Hello:

       In my project I met a issue,my M3Vpss will hang when run few days,below is terminal log:

[m3vpss ] Unhandled Exception:

[m3vpss ] handle: 0x3ec92fd8.

I have check the dvr_rdk_m3vpss_release_1024M_256M.xem3.map,get the below information:

3ec41fe0    0001dcec     hdvpss_drivers.aem3 : vpsdrv_m2mCompPriv.oem3 (.bss)
3ec5fccc    00000014                         : vpshal_rf.oem3 (.bss)

3ec8fce0    00015000     MAIN_APP_m3vpss_pem3.oem3 (.bss:ti_sysbios_heaps_HeapMem_Instance_State_0_buf__A)
3eca4ce0    000109a0     dvr_rdk_bios6.aem3 : ipcOutM3Link_tsk.oem3 (.bss)

3ecc5680    00010000                        : ipcInM3Link_tsk.oem3 (.bss:taskStackSection)
3ecd5680    00010000                        : ipcOutM3Link_tsk.oem3 (.bss:taskStackSection)
3ece5680    00010000                        : sclrLink_tsk.oem3 (.bss:taskStackSection)
3ecf5680    0000d838                        : ipcInM3Link_tsk.oem3 (.bss)

I think the stackbase is  displaylink,but the handle is MAIN_APP_m3vpss_pem3.oem3 (.bss:ti_sysbios_heaps_HeapMem_Instance_State_0_buf__A)

and the PC pointer is 0x00000002,this is valid address?

maybe you can give me some advice to debug this issue,current I don't which part lead this issue?

should I need use simulate to debug this issue？

best wish to you!
