>
>Many peoples have reported problems running Apache 1.1.1 (latest non-beta
>version) and Stronghold 1.3.2 (latest non-beta version) under Linux 2.0.x.
>I'm one of these persons, and I believe that Linux is the culprit. So I
>experimented a bit, and here are my results. But first, the facts:
>
>Here's my primary server:
>Pentium 133, with Intel 430FX
>64 Megs RAM
>Adaptec 2940 with 1gig Hard drive and tape backup
>NE2000 compatible network card
>IDE CDROM
>Linux 2.0.0
>
>And my development workstation:
>PentiumPRO 200
>48 megs RAM
>Adaptec 2940UW with 2 gigs Hard drive
>Kingston network card (DEC 21041)
>Linux 2.0.27
>
>That's the starting configuration. Both works perfectly with Stronghold
>1.3.2.
>
>Now, I wanted to upgrade the server to 2.0.27 to fix various security
>problems (mostly the ping of death). After upgrading, stronghold gave
>problems: The web browser would successfully pull the 4 first files for
>each page then wait for a long time for the fifth then fail. My Netscape
>is configured to open 4 simultaneous connections - I don't know if
>there's a connection between those values as I haven't experimented.
>So I decided to upgrade kernel by kernel to see where the problem arized.
>I did not exactly try all the kernels between 2.0.0 and 2.0.27, but I did
>a binary search, trying 2.0.0, then 2.0.14, then 2.0.20, then 2.0.24.
>All of these worked, compiled with the same options.
>Then 2.0.25 didn't work. So I applied manually all the diffs included in
>patch-2.0.25 to see which one broke stronghold, and I found the one
>included at the end of this message. Now since I'm no network guru, I
>have no idea what to do now, except post this here...
>
>Please note the following :
>- - Stronghold works with linux-2.0.27 on my workstation which is not so
>dissimilar to my server, except the processing power, so this MAY be a
>kind of race condition.
>- - I have not tried 2.0.26
>- - both computers have the same compiler, libraries, etc...
>- - The workstation runs X11, not the server
>- - The problem shows up reliably, even just after bootup, with minimal load.
>
>I am willing to do some further testing if deemed appropriate by any
>kernel guru.
