vApplicationStackOverflowHook with custom partitioning and 4MB flash size

I am trying to create custom partition with 4MB flash size. First I have increased the flash size through `menuconfig` then I've selected custom partitioning in `menuconfig` My partitions.csv is the following.
Code: [Select all] [Expand/Collapse]
  1. # Name,   Type, SubType, Offset,  Size, Flags
  2. # Note: if you have increased the bootloader size, make sure to update the offsets to avoid overlap
  3. nvs,      data, nvs,     ,        0x6000,
  4. phy_init, data, phy,     ,        0x1000,
  5. factory,  app,  factory, ,        0x200000,

The project is built and flashed properly. But it is crashing in a reboot loop with this error message.

What does the code do; is there a possibility you actually have a stack overflow somewhere? Why do you think the partitioning is related?

Try to increase main task stack in menuconfig.

I found out the problem was that I was including a class which has a big array. I removed that array then it worked. Possibly it was exploding the stack size.
