[ECOS] Memory leakage problem with GoAhead web server

[ECOS] Memory leakage problem with GoAhead web server

[John Mills]

All -

I'm working on an embedded eCos/MIPS32/OpenSSL product which I recently 
converted from eCos' basic 'httpd' to the free version of the 'GoAhead' 
server. Now I experience memory leakage.

I test with a simple script that repeatedly invokes 'wget' to request the
default index page over an 'https' link, and find the web server gradually 
claiming more and more dynamic memory - until the server finally fails to 
accept new connections.

If other users have encountered this problem or could suggest ways to 
narrow the diagnosis, I would really appreciate hearing about it.

TIA.

Check the archives - this problem has been reported many times.
I don't recall if a [proper] solution was ever found.

Gary, eCos users -

Thanks. A search of eCos archives did turn up a lot of references - most
centering on GoAhead's 'socketSelect'. There was also one (c/o Grant
Edwards) regarding secure links and authorization which might be exactly
my problem, but I didn't find any detail on it. Does anyone have a
specific pointer to that issue?

Thanks.

I'll look through my ecos source tree to try to see what I was
talking about...

I think I was referring to this problem from the above newsgroup:

________________________________________________________________________

Message-ID: <3AA29C31.385A367@attglobal.net>
[...]

I implemented this suggestion under Windows 2000 and now GoAhead traps when
loading home.asp.  Does not trap with a html page (vs. asp) (at least not
with the one I tested with).
