Re: [lwip-users] Lwip tcp-stack reliability issue when using non-reliable network?

[Itzik Levi]

Hi Sylvain,

Thanks for the response!

Just tried disabling both CORE_LOCKING and CORE_LOCKING_INPUT and unfortunately encountered the same problem.

I'm probably missing something, but what... loss-less stream works excellent, without any corruption, might be some kind of internal tcp queue corruption while congested?

Could you try without core locking support ? It's pretty new and not
tested as much as our "standard" message box sequential API.

You can stop trying to change memory pools size... Whatever the memory
settings are, you shouldn't have a corrupted TCP stream...
