Re: [ECOS] Mbufs leak- inputs

Hi Saritha,

May i know which  TCP/IP stack you are using in ecos ? Even through i
did not work with ecos. I did couple of projects with  lwIP and uIP stacks.

If it is lwIP TCP/IP stack look at the opt.h file and try to increase
buffer size and change that in lwipopt.h. I cannot think of anything at
this point. Unless in know which stack you are working with.
