CONFIG_HEAP_MEM_POOL_SIZE > 8192 creates system reset

[khodidas]

Hi, 

I am using ncs 1.5.0 and modem firmware version 1.2.3. 

if I keep CONFIG_HEAP_MEM_POOL_SIZE=8192 then my application runs without any issue but 

If I set CONFIG_HEAP_MEM_POOL_SIZE > 8192 (e.g. 16384 ) then systems keeps resetting while I try to allocate memory using k_malloc.

Earlier I was using 1.4.1 ncs. 

With that I was not facing any issue even with CONFIG_HEAP_MEM_POOL_SIZE=32768 heap size setting. 

Can you help me in resolving this issue ?

Regards,

I seem to have a similar problem when using v1.5
