Then go to ST, "mixed" and "quite the same" is not the thoroughly tested 
server in the contrib tree. It is your code, your debugging. If you need 
help, please post the changes.

it might be "very simple" but it is your CGI, your code, your debugging. 
If you need help, please post your code (in a synthetic format, please, 
we just need to see where you call lwIP functions and your return values).

You seem to have a memory trashing problem, it is either one of the 
tasks, your server, your CGI, or as Simon pointed out your (ST's ?) DMA 
driver.
