Problem with Apache module when running mtom

I run mtom sample with a big file and run with Apache then it fails to send it and in the log file it show an error like this in mtom.log.

[error] http_client.c(455) Response error, Server Shutdown

[Fri Jan 4 10:36:36 2008] [error] mtom_client.c(149) Stub invoke FAILED: Error code: 82 :: Input stream is NULL in message context

But mtom sample works fine with simple axis server for this particular file.With apache when increase the size of the file with mtom sample then,it cause a big performance degrading.But with simple axis server it works much faster than with Apache.
