Re: [ECOS] eCos + goAhead probelm

["Amir Yiron" <amir at WavionNetworks dot com>]

After some more tests, I've got a stable web server when I call bopen()
with a bufsize of 1.25M !
(1M is still not enough - I could bring it to crash after a massive set
of requests... )
Does it make sense?

What is the malloc size you're using for balloc's malloc() to solve the
out of memory problem?

Thanks,

Recently,  I modify balloc() in balloc.c of goAhead.
I try to increase 64bytes at the line of  malloc() .  And the problem of 
out of memory disappeared.
So , I think it's not the probelm caused by eCos.
I think it's caused by goAhead somewhere that call balloc() and use 
wrong size.

Now, in my target, goAhead still unstable just like you say. Then I use 
very simple web page instead of default web page(home.asp).
It still unstable, but not crashed.
But it can work very fine when I use 'lynx' instead of other browser(IE, 
mozilla..).
I don't know what's the difference of behavior between lynx and other 
browser (IE,mozilla).

Hope this information can help you something.
