Memory allocation issue in MQX.

rpneeraj — Sun, 08 Feb 2015 07:10:22 GMT

I am facing issue, in which application need to allocate memory block of around 250 bytes again and again,same block is getting freed also but after a run of 1 day application is getting reset with alloc return value of MQX_OUT_OF_MEMORY.

I am not sure what is causing the issue.

Below is the log for tad command which tells about the memory.

0x1fffe7a0 0x7e0 2016 0x1000d Unknown mem type 0x25

0x1fffef80 0x20 32 System INTERRUPT_VECTOR

0x1fffefa0 0x1054 4180 Free

0x1ffffff4 0x10 16 System Unknown mem type 0x0

0x20000004 0x1130 4400 0x1000b TCP_TX_WINDOW

0x20001134 0x1130 4400 0x1000b TCP_RX_WINDOW

0x20002264 0xdd8c 56716 Free.

Do revert with your suggestions on this.

Thanks,

Yes, it looks like some memory leak. Unfortunately it is hard to say what could be reason for that behavior.

Could you please provide more information about this case?

We would like to know used MCU/board, version of MQX, tool chain (IDE), memory allocator (I suppose LWMEM) and part of code or descriptions what your application do.

Have a great day,
