(using jboss 4.2.2)
testing our analytics app with a large data file (1G csv) upload through the webapp ... can see file transfer on server in /tmp ... dies at about 400m

also using httpd as reverse proxy on server ... set all timeouts(that I can find) to 3 days

any thoughts ... similar experience ... suggestions would be appreciated

below is partial trace:
