I configured resin behind Apache 2.2.8 (windows x86-32bit) for a production website. Most time it worked smoothly, except that two strange problems happened when server was under load.
1. HTTP 503 When website was under load or during stress-testing, sometimes apache returned HTTP 503 temporarily not available, especially when the response size is really large (say ~100kB). If running a standalone resin, everything is ok. 2. Apache crash with status 3221225477 When website was under load, apache will produce such error log: [Sat May 10 22:42:27 2008] [warn] (OS 64)The specified network name is no longer available. : winnt_accept: Asynchronous AcceptEx failed.

[Sat May 10 22:42:32 2008] [notice] Parent: child process exited with status 3221225477 -- Restarting. I think these two problems may be related to mod_caucho.dll. Unfortunely, I could not write a simple code snippet to reproduce them. -Wesley
