Antwort: [Mod_gzip] (no subject)

Hi Giulio,


> I installed mod_gzip

which version (both mod_gzip and Apache)?
On which platform?
Statically compiled in, or some DSO loaded via mod_so?

"Installed" could mean a lot of different things ...

This will be limited to 60000 internally by mod_gzip:

 if ( dconf__maximum_inmem_size > (long) 60000L )
   {
    /* TODO: Some OS'es will have a 'malloc()' problem if the */
    /* in-memory size is greater than 64k so for now just set */
    /* 60k as the fixed upper limit. Expand this later. */

    /* NOTE: Testing has shown that for responses greater than */
    /* 60k or so the 'swap to disk' option SHOULD be used, anyway. */
    /* MOST responses will be far less than 60k. */

    dconf__maximum_inmem_size = (long) 60000L;
   }

It dooesn't hurt to try setting this to a value below
60k, but I don't expect any different result by that.

Nothing spectacular here, I think.

Oops. Quite interesting.
I would try first to nail this down in the area of the in-
stallation process (maybe you have a corrupted DSO file or
something like that?).
So please explain what exactly you did there.

Apache crashed, obviously while checking the configuration
directives.
Sounds like some of the configuration parsers has run wild
and points to a memory section it isn't entitled to access.
It might be a bug in mod_gzip (although I cannot reproduce
it with your configuration), or it might be a corrupted file
you loaded as "mod_gzip.so" etc..

First we would have to identify whether it is a bug or a
broken installation. Therefore ... see above.
