[lwip-users] mem_malloc fail

[PAUL . YU 喻浦軒]

Hi all,

I'm meeting a problem in SNMP protocol. The SNMP codebase (msg_in.c) will call the mem_malloc many times. If there has too many entries in the SNMP request table, I will always get return NULL ( memory allocate fail) after called mem_malloc 13 times. I try to increase the MEM_SIZE in lwipopts.h and OS heap/stack size, but they all doesn't work.

Do you have any suggestions about this ?

I'm using lwip 1.2.0 and FreeRTOS 5.2.1

Thank you!
