Thank you for the information regarding these parameters.
I am seeing a problem with the service I have written where in I receive
an MTOM attachment from client and the service sends back the same
attachment.
Problem description:
As per my observation apache_http_server uses around 5.5MB of
memory in idle state(When it is not serving any request).When I invoke
the service to send an attachment of size around 145MB. The memory usage
of apache_http_server went up and as I observed it went up to 601.1MB
and my computer slowed down significantly.I am unable to figure this
out.I have worked with other frameworks like
axis2/java,gSOAP,Glassfish.I never came across such problem even when I
transferred 1GB files across.I have specified my computer configuration
below.I have attached axis2.xml file used while running server. I am
using default values MTOMChunkBufferSize is 1 and MTOMMaxChunkBuffers is
1000 please refer attached axis2.xml.Kindly let me know as to where I
have gone wrong.
Computer Specs:
CentOS 4.4 on VMWare(host Windows xp)
1GB RAM

Also I think it's better to update the Axis2/C manual. And add another
entry to Axis2/C FAQ.
