Subject Re: Problem with Ubuntu
Date Thu, 01 Oct 2009 03:16:40 GMT
Hi,

Can you run using simple axis server and see whether it crashes? When
you are debugging httpd with -X flag, it runs in a single process.
That might be the reason why it works.. If it crash it simple axis
server, it might be easy to debug.

Regards,
Shankar
